and lives are saved. jeremy corbyn announces that labour will pay 16 and 17—year—olds the same minimum wage as everyone else if it wins the next election. fly—tipping in england is up by nearly 40% in the past five years. and councils say nobody has yet been given the maximum sentence. i felt harassed, i felt like, how can somebody say that they would rape me first and be a legitimate candidate in an election. —— would rape me if forced. and just one of the 10,000 messages of abuse labour mpjess phillips says she's had. she spoke to the victoria derbyshire programme. you can see that interview in half an hour. good afternoon and welcome to bbc news. concerns over climate change might restrict the growth of aviation in the uk, the government has admitted. a senior civil servant says ministers may have

to review their strategy, including plans to expand heathrow. it follows a recent warning from the committee on climate change, which advises the government, that the planned increase in aviation would need to be curbed to control carbon emissions. 0ur environment analyst roger harrabin reports. flying is on the up and the government has been planning for it to continue to grow. what about climate change, you might ask? well, under current policy, industry will have to cut more greenhouse gases so aviation can expand. but the government is now considering a plan to virtually eliminate emissions by 2050. and a civil servant has admitted in a letter to a green group that it may have to take note of advice from the independent climate change committee, saying that although people could continue to fly while meeting climate change targets, it was not possible for aviation to keep on expanding. in the end, i think the logic of this is completely inevitable.

we know that we have to reduce our emissions urgently and radically and expanding them is going in the opposite direction. itjust does not make sense and i don't think the public want to see the government committing to a plan that is inconsistent with a safe and prosperous future for all of us. any policy change may affect controversial plans to expand heathrow. it definitely means the government will have to think hard about whether aviation can continue to grow at a time of what parliament calls a climate emergency. roger harrabin, bbc news. the united nations says houthi rebels in yemen appear to be honouring a pledge to withdraw troops from key ports. it's the first signficant step since a ceasefire agreement was signed in december. the three ports are crucial for the distribution of international aid in a country where millions are on the verge of starvation. for the last four years, the houthi, supported by iran, have been fighting the yemeni government, which is backed by a coalition of countries led by saudi arabia.

awarning, this report from the bbc‘s chief international correspondent, lyse doucet, contains some distressing scenes. a vital lifeline for a nation on the brink of famine. nearly all of yemen's aid comes through here. the houthis control this port and two others nearby. now they say they are pulling out theirfighters. if they do, it's the first step in the deal reached in stockholm in december, hailed then as a rare breakthrough. now the deal is on the verge of collapse. so is yemen, a country facing what the un calls the world's worst humanitarian crisis. images like this have shocked the world. not enough to end a brutal war between houthis aligned to iran and yemen government forces backed by a saudi—led coalition and armed by the west.

earlier this year we saw how a fragile ceasefire in hudaydah was largely holding. but both sides agreed in stockholm to withdraw their forces from this strategic corner of yemen. there is deep distrust. if this first step succeeds, it could lead to broader peace talks. if it doesn't, yemen's best chance in years could also fail. lyse doucet, bbc news. the united states says it's ready to defend its forces and interests in the gulf as tensions with iran escalate. the pentagon is sending an extra navy vessel and a patriot air defence missile system to the region, but said it was not seeking conflict with tehran. two men have appeared in court charged with rioting offences in londonderry on the night that journalist lyra mckee was killed. the men are accused of riot, petrol bomb offences and arson of a hijacked vehicle. ms mckee was shot dead while watching disturbances in londonderry last month.

0ur reporter louise cullen is in belfast and has this update. two men appeared in court in londonderry magistrates‘ court. they were 51—year—old paul mcintyre from ballymagowan park in the creggan area of londonderry. and 38—year—old christopher gillen, who is from balbane pass in the city. both men are charged with riot and petrol bomb offences. paul mcintyre is also charged with arson of a hijacked vehicle, while christopher gillen is also charged with the arson and hijacking of a tipper truck. both men refused to stand and acknowledge the court when they were brought into the dock. a detective said that the evidence against the men had come from mobile phone footage handed in by members of the public and also from footage seized from a documentary being filmed by mtv on thursday april 18th in derry, which included filming in the offices of the dissident republican linked group saoradh in derry and also rioting in creggan during which lyra mckee was shot.

he also said he believed the two men ringleaders. the two men were ringleaders. both men were denied bail when thejudge said he didn't believe there was a safe address in the city, at any stage, for them to be remanded to and they were both remanded in custody. labour say if they win power, they will change the minimum wage, so that 16 and i7—year—olds will be paid £10 per hour, up from the current rate of £4.35. it would put them on the same rate as that pledged by labour to older workers. some business leaders say it could risk reducing the number of under 18—year—olds in work, especially apprenticeships. here's our business correspondent katy austin. how much should you pay a young person to work for you? workers in the hospitality and retail sectors are the most likely to be on the lowest pay. today, labour says the youngest employees should be paid more. we will abolish the youth rate of the minimum wage.

workers should be rewarded fortheirwork, not theirage. equal rights for workers means just that, irrespective of age, gender, nationality or ethnicity. at the moment, the independent low pay commission advises the government on what the minimum wage should be. workers under the age of 18 are currently entitled to a minimum wage of £4.35 per hour. for over 25s, it is nearly double that, £8.21 per hour. under labour's plan, a £10 per hour real living wage would extend to people under 18, adding, it says, £2,500 to the amount 16 and 17—year—olds earn each year. this is a very big change, we do not know what the effect would be because nothing like it has been tried before. this is more than doubling the minimum wage for 16 and 17—year—olds. the risk is that employers might not want to take them on at £10 per hour and the particular risk is,

if this applies to apprentices, it may reduce the amount of training some of these young people are getting. labour says it would give smaller firms support to help them afford the rise, saying it would use savings from a reduction in the amount the treasury pays in in work benefits to pay for it. the group representing small businesses told me firms are already squeezed and it wants to hear more detail about exactly what support would be on offer to help them shoulder the cost and avoid job cuts. the conservative vice—chairman for policy said... labour's idea is clearly designed to appeal to younger voters. the verdict from businesses, more detail needed. katy austin, bbc news. the chairman of the 1922 committee of backbench conservative mps, sir graham brady,

says he expects theresa may to give more detail in the coming days about her plans to leave downing street. the prime minister is due to meet the committee's executive next week. earlier i spoke to our political correspondent jessica parker, who said that sir graham has asked for clarity from theresa may. i think he would say he represents the views of backbench conservative mps and let's be clear, those views do vary somewhat, but there are certainly some conservative mps, i think increasingly this is the case, who want theresa may to set an unconditional timetable for her departure, because at the moment, what she has said is that she will go once phase one of brexit is delivered, the withdrawal agreement, the divorce settlement, if you like, of leaving the european union. sir graham brady, he has said, talking to the bbc, that he does understand why the prime minister might be reluctant at this stage to name an exact date. i do not think it is about an intention of staying indefinitely as prime minister or leader of the conservative party, i think the reticence is the concern

that by promising to go on a certain timetable, it might make it less likely that she would secure parliamentary approval for the withdrawal agreement rather than more likely. how likely is it that she will have to go of her own accord rather than being given the shove? look, who can say exactly what will happen over the coming days and weeks? what sir graham has also said is he thinks it would be strange if this meeting did not result in some clearer understanding of theresa may's plans for her departure, but theresa may still wants to secure some kind of brexit legacy and if she does feel that by naming the exact date, that means that those opponents of her deal are more likely to dig in rather than relent, because they can see her departure date in sight, perhaps she will not want to name an exact date, so they might ask for that this coming week, but there is no guarantee that they're going to get it. does sir graham want to throw his hat into the ring for any leadership battle? he hasjoined the many people who have said they are not ruling it out.

gunmen have killed at least one person in an ongoing attack on a luxury hotel in south west pakistan. reports from the port city of gwadar in baluchistan suggest gunfire is continuing between the security forces who've rushed to the scene and gunmen who've entered the pearl continental hotel. guests have been evacuated but some hotel staff may still be inside. fly—tipping has increased by almost 40% in the past five years according to councils in england. the local government association said nobody convicted of fly—tipping since 2014 had been given the maximum penalty of a £50,000 fine or a year in prison because of funding pressures. the goverment says they've strengthened local authorities‘ enforcement powers. i'm nowjoined by guy smith, deputy president of the national farmers' union and joins us from their offices in central london.

his farm is near clacton—on—sea and essex. thank you forjoining us. how familiar is the story of increasing levels fly—tipping? familiar is the story of increasing levels fly-tipping? this will come as no surprise to farmers. approaching 1 million cases, and many farmers will tell you this is not the whole picture, because many farmers like me do not bother to report it, wejust farmers like me do not bother to report it, we just cleared it up out of her own expenditure, because we are fed up with reporting it and nothing happening, so it is underreported as well. what sort of experience have you had? for a farmer close to a conurbation, if this is not a daily occurrence, it is weekly. refrigerators, sofas, household waste, and for some farmers, particularly in south essex, 25 tonnes of recycling waste being bashed through fortified gates, kept up and that is organised crime. why has it got so much worse?

it is commercially attractive for a company to it is commercially attractive for a com pa ny to clear it is commercially attractive for a company to clear someone pass my garden and take the rubbish out of the garage and have a few quid, and then dump it into a farmer's field 01’ then dump it into a farmer's field or into his dig in the knowledge that the risk of being detected is low and if it does come to court, the fine will be low, so it is commercially attractive. what sort of damage can it do to your land, crops, animals? farmers take immense pride in the beauty of their farms, hedges and whatever, and to see it used as a rubbish tip is depressing and frustrating. it makes farmers angry. we take pride in the beauty of ourfarms, and to angry. we take pride in the beauty of our farms, and to see them abuse like this, it is depressing. the powers exist to bring people to court, so what is the solution in your view? we have heard the several report on the government response to this, that they have increased powers but it is clear it is not

working. the government needs to speak to local authorities and police to find out how we get this to work, how we have effective deterrents. —— defra report. iwould also plead to your viewers, if people are saying they will take away your household waste, make sure they are a reputable company with a landline, with the waste disposal carrier's license. if they are a cheap deal, ask yourself why is that? we would implore locals astori trees —— we would employ local authorities not to close community tips because that makes it difficult to get rid of household waste, but it isa to get rid of household waste, but it is a false economy up where it is not put what it needs to be, and we would implore central government to realise that they need to have a summit between police and local authorities to find out how they can unlock this increasing problem. how do you go about disposing of these pieces of furniture, these

refrigerators we have been seeing pictures of. it is obviously at a cost to you ? pictures of. it is obviously at a cost to you? yes, someone has dumped their problem on me and i am not allowed to put this on a trailer or allowed to put this on a trailer or a van and take this to my community tip, because it is deemed that i am operating some sort of commercial waste facility and i am turned away. it isa waste facility and i am turned away. it is a real dilemma for me. i will not just leave them it is a real dilemma for me. i will notjust leave them there. i will have to dig into my own pocket. some councils are more helpful than others. i accept that. for me, this is just cost. the headlines on bbc news: concerns over climate change might restrict the growth of flying in the uk, according to a senior civil servant. aid workers say a pledge by houthi rebels in yemen to withdraw troops from key ports is a "big game changer", as it may open a lifeline for millions of people facing famine.

jeremy corbyn is pledging that labour will pay 16 and 17 year olds the same minimum wage as everyone else if it wins the next election. in sport, jos buttler smashes a quickfire century as england pass my cricketers that pakistan an impressive target of 373 in the second one—day international in southampton. pakistan are 61 without loss after nine overs. aston villa have the advantage in their championship play—off semifinal against west brom. they w011 semifinal against west brom. they won the first like to —— one at villa park. the second leg is next tuesday. wsl champions arsenal finished the season on a wsl champions arsenal finished the season on a high, beating nearest rivals man city 1—0. it was city's first league defeat of the season. a hat trick of pole positions for va ltteri bottas hat trick of pole positions for valtteri bottas as he gets the better of his mercedes team—mate lewis hamilton once again. he will start the spanish grand prix tomorrow from second. more sport at half past five.

a 74—year—old pensioner who was shot with a crossbow bolt as he adjusted his satellite dish at his home in holyhead, on good friday has died. the bolt had travelled through gerald corrigan's upper body, narrowly missing his heart and then passing through his right arm. north wales police said he died as a result of the horrendous injuries he sustained. in just 12 days' time voters will be asked to elect 73 representatives into the european parliament. the delay in a brexit deal being decided means the uk is obliged to take part in the european elections on the 23rd may. tim muffet has been to grimsby, which overwhelmingly voted to leave the eu, to see what businesses and residents think about the vote. gutted. that's howjohn feels about the uk's participation in the european elections. i think it's absolutely disgraceful and i think we should have been out now. will you take part in the elections? no.

what is the point of voting when that is not what we want to do? this is the alfred and enderby smokehouse in grimsby. the way we traditionally smoke haddock and salmon is unchanged for centuries. the tannins and the flavours within the fabric of the building are part of that taste. when it comes to the european elections, for some employees there is also a whiff of anger. i don't think we should be in europe in the first place. it is a waste of time and a waste of money. in the 2016 referendum, grimsby was one of the most pro brexit parts of the uk. 70% of those who voted, did so to leave the eu. for this company, eu rules and regulations play an important role. we have a protected geographic indication and that is something that is given not easily by europe. things like parma ham and champagne. in lincolnshire there is only one

protected name and that is grimsby traditional smoked fish and it took several years to get that. how do you feel that we will take part in the european elections? we do need to be engaged. if we stay in, and there is every chance we may, we want someone in there who will represent our interests. the fishing industry in grimsby dates back over 1000 years. the legend has it that the town's name came from a danish fisherman named grimm who settled here. today it lies within a european constituency of yorkshire and the humber. they have not delivered on brexit. it is just a big circle whether common man is not being listened to. those who voted to remain will be more serious this time. do you think there has been a change since the last european election because of the referendum? yes. i don't really know about europe,

ijust know about brexit and what we were supposed to get and what we did not get. this constituency elects six meps. last time it picked two from labour, three from ukip and one conservative. this time they will be up against english democrats, liberal democrats, change uk, the green party, the yorkshire party and the brexit party. confused. you don't know what direction to look in. it is probably not in everybody's face as it should be. i don't care. i'm not interested. probably fixed and all that, anyway. if brexit has made some more engaged with politics, it is had the opposite effect with others. political changes across the north sea leave many here cold. you can find out more about who is running in the european elections on the bbc news website. now, with the campaign for the european parliament

elections underway we're going to be speaking to all the main uk parties here on the bbc news channel over the next few weeks. and we want you to send us your questions. on tuesday at 5:30 we'll have nigel farage of the brexit party, then the next day at the same time chuka umunna on change uk. you can email us at askthis@bbc.co.uk, text 61124 or use social media with the hashtag #bbcaskthis. an event aiming to reunite families separated between mexico and the united states has been cancelled after organisers said the american authorities refused to give permission. the gathering, called "hugs not walls", allowed families to meet in an area between frontier crossings near the texas city of el paso. the organisers have blamed president trump for the cancellation. david willis reports. along the dusty border that separates mexico from the united states, families are separated.

migrants who enter the united states illegally would face arrest if they attempted to cross here, an annual event offered some respite and a brief chance of reunion, until now. called hugs not walls, families met at this canal between the mexican state of chihuahua and the american state of texas. but us border patrol has denied permits, and this weekend's event have been cancelled. translation: this is the real impact of trump's policies on the border. the agencies we have worked with have been inflexible. maria was one of many who had registered to take part in the event. translation: i would have liked to have seen the family on mother's day. i have to accept, i can't

cross the border, ijust have to accept things. thousands of migrants have arrived in mexico in recent months, most of them from central american nations where poverty and violence is rampant. president trump has declared them "threat to national security", and it was announced that $1.5 billion has been allocated from the us defence department to help fund his much—vaunted wall along the southern border. david willis, bbc news. lgbt models were on the catwalk at an event showcasing pakistani fashion in london this week. it also featured britain's first muslim transgender drag queen. 0rganisers say it was a nod to the passing of a recent bill in pakistan which banned discrimination against transgender people. bbc asian network's shabnam mahmood has more. music a pakistani fashion show with a difference. these models are all

from the lgbt community. making her debut, britain's first out muslim transgender drag queen. within the last year in pakistan, there has been quite a lot of government bills that have gone through, especially around transgender rights. i think actually pakistan fashion week highlighting that within the fashion runway, i think is a really great move forward. strutting their stuff during rehearsals. it's the first time the event is featuring a transgender catwalk since it began almost ten years ago. the world is progressing and pakistan progressed. i thought why not give it a shout as being celebrating freedom. fashion has no boundaries, i always say, so why limit the fashion for any gender, for any person, any race or any caste. fashion is for everyone. last year, pakistan's parliament passed a law protecting its tra nsgender community and banning discrimination against them.

this show is celebrating the landmark move. teaching people to be tolerant, accepting of one social issue will potentially create more equality for all. particularly for this line it's important for me to show visibility and solidarity for other communities other than the transgender community. a lot of people don't actually realise how many ethnic, notjust black, but ethnic, gay people there are out there. it is a high community and i wish to bring out awareness to it. and the clothes on display have been made to appeal to all sexes. i do understand that our brands are primarily focused to define genders, like either do a men's line or a female line. but the world is moving into different directions, like we have come up with this unisex range which caters to all kinds of ranges. who am i to discriminate against who wants to wear what? 0rganisers are hoping gender neutral

fashion will become a permanent feature in their future events. shabnam mahmood, bbc news. now it's time for a look at the weather with chris fawkes. hello there. it has been a day of sunshine and showers with dramatic clouds filling the skies across central and eastern england, clouds like these, cumulonimbus clouds threatening skipton in north yorkshire. thanks to our viewer for sending that weather watcher picture in. now those showers lasting across eastern england for a time during the next few hours so there are still some heavy downpours around, potentially a rumble of thunder, but essentially those showers will fade away as we go through the night, and with light winds and clearing skies it will be a cold night, cold enough for temperatures in the towns and cities to get down to low single figures but head out into the countryside and you will notice some blue on the charts, yes, there will be patches of frost to start the day on sunday, so a chilly start to things, but plenty of sunshine throughout the day across most of the country thanks to high pressure building. that said, high cloud in

the western isles making the sunshine hazy and showers for the northern isles, but otherwise dry. 16 in edinburgh and manchester, 17 in cardiff and london. that is your weather. hello, this is bbc news with martine croxall. the headlines: concerns over climate change might restrict the growth of flying in the uk,

according to a senior civil servant. the un says houthi rebels in yemen appear to be honouring a pledge to withdraw troops from key ports, opening a lifeline for millions of people facing famine. jeremy corbyn announces that labour would pay 16 and 17—year—olds the same minimum wage as everyone else if they win the next election. equal pay for equal work is hardly a controversial idea, so why are we discriminating against young people? fly—tipping in england is up by nearly 40% in the past five years. the local government association says nobody has yet been given the maximum sentence. and now on bbc news, victoria derbyshire takes a look back at some of the highlights from her programme this week. hello, welcome to our programme.

over the next half—hour, we will bring you some of the exclusive and original stories we have broadcast over the last week. this week, the labour mp jess phillips revealed to us she estimates she has had more than 10,000 messages of abuse directed at her over social media. at one stage, she says, the vitriol was so overwhelming she burst into tears in public, partly blaming herself, because she believed she had not done enough to try and change the law to try and stop online abuse. yes, actually, ithink it is shocking it is still happening because we've been having this conversation for what feels like about five years, that politics has become feral, that threats against politicians and candidates and people, political activists, it is not a new thing. we still seem to not be able to get through the drudge of it. this is what carl benjamin said in his video, if you're 0k for me to quote him. i know you have not watched it yourself and it has now been taken down from youtube.
