lay bare the challenges we are all facing. give us your view on how governments and businesses respond to this. i hope they respond with urgency, despite all the progress we still have more greenhouse gases today than ever before. it is not enough to build windmills and solar panels and electric cars, we have to take metal goals of the road, get the gas out of our homes and replace with electricity, and take polluting powerplants take polluting powerpla nts off—line take polluting powerplants off—line today, this year, this decade. off-line today, this year, this decade. �* . ~ , , decade. and it makes it very clear, decade. and it makes it very clear. the — decade. and it makes it very clear, the report, _ decade. and it makes it very clear, the report, when - decade. and it makes it very clear, the report, when it. decade. and it makes it very clear, the report, when it is| clear, the report, when it is finally released that actually we are in a position where we cannot delay any further, because since the war in ukraine began, in many cases, governments and organisations have actually gone hold their climate targets for various reasons. climate targets for various reasons-— reasons. it's been a challenging - reasons. it's been a challenging couple l reasons. it's been a l challenging couple of reasons. it's been a - challenging couple of years.

no limits partnership. but it is not an equal one. russia, under heavy international sanctions, is increasingly dependent on china as a market for its goods and raw materials. as for no limits, well, there are some. up till now beijing has been reluctant to provide russia with lethal aid for the ukraine war to avoid secondary sanctions against chinese companies. still, china is thought to be supplying dual use technology like semiconductor chips that can be used by russia's military. ahead of the summit, president putin paid his first visit to territory that russia has captured and occupied during its full—scale invasion of ukraine. he toured mariupol, a city reduced to rubble by russian shelling. his presence and a clear message to ukraine the west — there will be no

compromises by the kremlin. steve rosenberg, bbc news, moscow. let's get some of the day's other news. president biden has expressed concern to the israeli prime minister, benjamin netanyahu, about his plans to overhaul the judicial system. in a phone call, mr biden offered support for finding a compromise. huge protests against the reforms have taken place across israel for the past 11 weeks. central banks in europe and north america have welcomed financial markets in asia have started the week's slightly lower. the hang seng index fell by more than 3% at the open. chocho's nick kay down by nearly a cent. —— tokyo. there will be co—ordinated action to ease market strain. that is our top story in business today. in 20 minutes we will go live to switzerland for a reaction to the news that credit suisse is to be bailed out by its

civilians, as well as fighters, were killed. the rise and fall of islamic state, also known as isis, was part of an unfolding catastrophe that engulfed iraq and was felt right across the middle east. now, a loss of this goes back to march 2003. that was when the americans and their british and their allies invaded iraq. the americans called the massive air raids with which they opened the war shock and all. they claimed, wrongly, that this was the way to make the middle east safer for everyone. within weeks they had removed the iraqi dictator saddam hussein. anotherfalse saddam hussein. another false claim saddam hussein. anotherfalse claim was that he had weapons

other cities has been rebuilt. there are bright spots. as for the west, the americans and the british, the invaders, a lot of the world just loves when they talk about piece or international law because of what happened here. but what matters most is the effect on the lives of millions of people, notjust in iraq, but across the wider middle east who suffered and died because of the invasion and its consequences. jeremy bowen, bbc news, mosul. stay with us on bbc news, still to come: a new initiative to encourage people across the uk, to volunteer for community projects over the coronation weekend. applause

this is bbc news. the latest headlines: the most comprehensive study yet on the the impact of climate change is due to be released by un scientists after 8 years of research. vladimir putin prepares to welcome chinese president xijinping to moscow for talks — one of his last remaining allies on the world stage following russia's invasion of ukraine. the french government will face a no confidence vote on monday after president macron used controversial executive powers to raise the state pension age from 62 to 64. the government says the changes are needed to avoid crippling deficits in the coming decades linked to france's ageing population. but opponents say the law places an unfair burden on low earners, women, and people doing physically wearing jobs. sofia bettiza reports. chanting. another day of anger in the streets of paris.

french people have been protesting for months against a government plan to raise the pension age from 62 to 64. but in the last few days, things have escalated. there is outrage at president macron. he's invoked controversial executive powers to force through his reform without a vote, essentially bypassing parliament. and outrage turning to violence in many cities across france. more than 160 people were arrested on sunday. sirens wailing. and on monday the french government will face a no—confidence vote. but the vote is unlikely to pass, as it would require a united front across the political spectrum. which means that mr macron�*s pension legislation is likely to be adopted on monday.

it's a deeply unpopular reform, which has led to months of strikes, including garbage collectors in paris. this is what the streets of the french capital look like now. more than 10,000 tons of rubbish piling up and left to rot. translation: this situation is catastrophic for the residents, | for the tourists, for the whole of paris. the most beautiful city in the world — rats during the day, endless rubbish bins. it's very, very dirty. translation: it's not - the rubbish collectors' fault. it is macron's fault, if he had let parliament vote — a vote which he must've thought he'd lose — we would be back at work and we wouldn't still be striking today. it is in no doubt that president macron is facing one of his biggest challenges, just less than a year into his second mandate. chanting.

and with more crippling strikes to come, police are bracing for another week of anger and protests. sofia bettiza, bbc news. to celebrate the coronation of king charles, 1500 charities will be offering people the chance to volunteer during the bank holiday weekend in may. 0ur royal correspondent, sarah campbell has been to visit one of them and has more on what's being called the the big help 0ut. across the uk there is an army of volunteers giving up their time and sharing their talent and expertise to the benefit of all. i and expertise to the benefit of all. . , and expertise to the benefit of all. ., , ., all. i have been involved in scouting — all. i have been involved in scouting for _ all. i have been involved in scouting for 22 _ all. i have been involved in scouting for 22 years. - all. i have been involved in scouting for 22 years. it. all. i have been involved in scouting for 22 years. it is | all. i have been involved in| scouting for 22 years. it is a satisfaction. seeing them and enjoying themselves and being part of it is like being part of one big family. i

the 2—1 victory gives xavi's side a 12 point lead at the top of the table — with 12 games to go. manchester united are through to the semi—finals of the english fa cup, after coming from behind to beat fulham in an ill tempered match at old trafford. aleksandr mitrovic had put the visitors ahead in the second half, before willian was sent off for this handball on the line. mitrovic protested the decision and saw red himself for this altercation with referee chris kavanagh. fulham boss marco silva wasn't happy and he too as sent off for something he said to the officials. bruno fernandes' penalty levelled the tie, marcel sabitzer put the hosts ahead, before fernades sealed the 3—1 win in stoppage time. evenif even if i have not done something special, i have to control it better myself, of course. it should be in my

area. i didn't say anything really special to the referee. he did not listen to what i said, for sure. he did not listen to what i said, forsure. he he did not listen to what i said, for sure. he gave me the red card because in that moment but it is a moment to control the emotions of the game. red bull's perfect start to the new formula 1 season continued injeddah with a one—two at the saudi arabian grand prix. sergio perez, who started in pole, crossed the line first, ahead of team mate max verstappen. it was a reverse of the result in the season opener in bahrain. aston martin's fernando alonso was third with the mercedes duo of george russell and lewis hamilton in 4th and 5th respectively. elena rybakina has won the first wta 1000 title of her career. the wimbledon champion saw off aryna sabalenka in the bnp paribas final in indian wells. the belarussian won the last meeting between these 2, at the australian open final injanuary. but the kazakh got revenge for that defeat, coming through in straight sets. sabalenka hit 10 double

live to switzerland in a moment. see you then. hello. we'll need our raincoats and brollies this week. it really does look very unsettled indeed, and especially wet in western parts of the uk. monday is no different. i don't think it's going to be raining all the time, but certainly some rain on the way and just a few glimmers of brightness. a lot of cloud streaming in our direction but you can see it's coming in from the southwest, hence it stays mild. and multiple weather fronts crossing the country through the course of monday. more weather fronts out in the atlantic making a beeline for the uk. so the forecast then for monday shows mild conditions early in the morning. temperatures around five degrees in stornoway, nine in plymouth. and see where the heavier rain is in the morning across parts

of northern england, southwestern scotland and northern ireland. that's one weather front, you can see it moves northwards. and then in the southwest later in the day, showers gather across cornwall, devon, parts of southern wales by around about 3pm. the best chance of any brightness would be across parts of the midlands, maybe east anglia, lincolnshire, perhaps yorkshire, and this is where will have the mildest weather up to about 16 celsius. elsewhere, the thicker cloud and the outbreaks of rain, it won't be quite as mild, closer to around 10—12 degrees. much fresher conditions in the north of scotland, with some sunshine in lerwick, about six or seven. through the course of monday evening, it does look as that rain would be more widespread and heavy as it spreads across the uk. here's tuesday's weather map, and a broad area of low pressure across the atlantic, sending weather fronts in our direction, quite a few isobars there, so that means the winds will be freshening as we go through tuesday and into wednesday. on tuesday, we are between weather systems, so one out in the north sea, another one here approaching ireland. we are in between with some sunny spells, but also some showers.

you can see heavy showers in one or two areas. again, very mild, 13 or 14, perhaps 15 degrees. through the course of the evening, the next weather front starts to sweep towards more eastern areas. through the course of wednesday, that big low pressure still dominating the weather across the atlantic. it's like a washing machine of clouds and showers circulating areas of low pressure. so, a very breezy day as well and gale force winds are possible around some western coasts. so, here's an overview of the week ahead, you can see most days have rain icons but, at least, it is relatively on the mild side. bye— bye. over the coronation weekend.
