is going up, people's pay isn't going as far. now nurses say they want a pay rise of 5% above the inflation rate. well the government's called on them to consider the impact on patients if this strike goes ahead. how likely is it they would get that kind of pay rise? we are going to hear the government's financial plans this month and hear proposed tax rises and spending cuts. when we hear the government, it seems agreement on wage increases ills not imminent. == wage increases ills not imminent. -- is not wage increases ills not imminent. —— is not imminent. wage increases ills not imminent. -- is not imminent. are _ wage increases ills not imminent. -- is not imminent. are any _ wage increases ills not imminent. -- is not imminent. are any of- wage increases ills not imminent. -- is not imminent. are any of the - wage increases ills not imminent. -- is not imminent. are any of the uk l is not imminent. are any of the uk nations going _ is not imminent. are any of the uk nations going to — is not imminent. are any of the uk nations going to offer— is not imminent. are any of the uk nations going to offer the - is not imminent. are any of the uk nations going to offer the sort - is not imminent. are any of the uk nations going to offer the sort of. nations going to offer the sort of money the nurses are looking for? no, none have offered the 5% above the 12% above inflation that nurses want. to give you an idea of how

much nurses the earn. junior nurses is around £27,000. that rises to 55,000 for the most senior nurses. in england and wales, nhs staff have been given an average of 4.75% more and in scotland they're offering a flat rate of £2,200 more. we are yet to hear from flat rate of £2,200 more. we are yet to hearfrom northern ireland. the department of health say they have consulted independent bodies and followed the pay recommendations and it wants the unions to think hard before striking. the nurses say they can't see a future in a profession thatis can't see a future in a profession that is not valued or treated fairly. that is not valued or treated fairl . ., ~' ,, the prime minister still has confidence in minister sir gavin williamson,

the lib dem leader also set out plans to help home—owners with mortgage payments. and he had this message for rishi sunak. (tx sor next) and he had this message for rishi sunak. this tsegai who two years ago was telling us all to eat out to help out. well, our message to the conservatives is this — help out by clearing out! rishi sunak, your government does not have a shred of credibility left. it does not have a shred of legitimacy left and if you had a shred of integrity left, you would call a general election now.

but when ever that election comes, the liberal democrats will be ready, we are the party that will end this chaos, the party that understands the challenges people are facing, we will show that we are the party that cares, the party that has a plan, the party that offers a fair deal and that is why we will win! sir ed davy there- _ the united nations cop27 climate conference got underway this morning in egypt with the outgoing chairman — britain's alok sharma — telling delegates that inaction will only defer climate catastrophe and asking, "how many more wake up calls does the world actually need?". the prime minister rishi sunak is flying in today along with other world leaders for the 12 day conference. our environment editorjustin rowlatt looks now at some of the issues on the agenda.

it has been a year of record—breaking temperatures and climate—related disasters, but africa has been hit particularly hard. huge floods displaced a million people in nigeria last month. cyclones ripped through madagascar and a year of low rain fall pushes parts of east africa closer to famine. it is easy to see why egypt said it should be a climate conference for africa. look at historic emissions. developed countries in places like europe and america got rich burning fossil fuels. lots of nations in asia are now doing the same. but take a look at africa's share. it is tiny. less than 8% of the total. that is the issue. developing nations say we didn't cause the climate problem, so why should we pay to fix it? egypt

says it is time for the rich world to come good on its promise of a hundred a million a year to helping developing countries adapt to the changing climate. there will be some new demands too. remember the floods in pakistan this summer? well the developing world is also asking for cash to help with the loss and damage climate—related disasters are already causing. damage climate-related disasters are already causing-— already causing. there is a lot of money for _ already causing. there is a lot of money for war— already causing. there is a lot of money for war for _ already causing. there is a lot of money for war for instance, - already causing. there is a lot of money for war for instance, you | money for war for instance, you know? in the system always when it is needed. 20 year there was a war next door. it was costing $300 million a day. so i don't think it is an impossible ask. last million a day. so i don't think it is an impossible ask. last week the head of the — is an impossible ask. last week the head of the un _ is an impossible ask. last week the head of the un warned _ is an impossible ask. last week the head of the un warned of _ is an impossible ask. last week the head of the un warned of a - is an impossible ask. last week the head of the un warned of a crisis i is an impossible ask. last week the i head of the un warned of a crisis of are trust if there isn't progress. but with a war in europe and soaring food and energy prices, wealthy countries warn they already have lots of calls on their cash. they

don't want to sign up to an open—ended commitment. the us climate enjoy told the bbc the world's focus should remain on trying to cut emissions to minimise future climate change. we trying to cut emissions to minimise future climate change.— future climate change. we have an enormous challenge _ future climate change. we have an enormous challenge ahead - future climate change. we have an enormous challenge ahead of - future climate change. we have an enormous challenge ahead of us . future climate change. we have an| enormous challenge ahead of us to stop the damage from happening. and loss of countries are contributing to that damage today. including in the developing world. so we have to move fast fast tore get off coal and reduce fossil fuel consumption. this real potential _ reduce fossil fuel consumption. this real potential for _ reduce fossil fuel consumption. this real potential for disagreement at the conference, the last conference ended with ambitious pledges, this year is about implementing the pledges and that is a much more ambitious task. in short, don't expect any big breakthroughs in

egypt. as we've been reporting, the un has said the past eight years are on track to be the hottest on record — bringing ever more impacts of climate change. let's speak to our correspondent at the conference. so much focus about who exactly was going to go there, it is finally under way, what has happened so far, bring us up—to—date. happened so far, bring us up-to-date-_ happened so far, bring us up-to-date. happened so far, bring us u-to-date. _, . , .,, up-to-date. the conference is open toda and up-to-date. the conference is open today and they _ up-to-date. the conference is open today and they have _ up-to-date. the conference is open today and they have adopted - up-to-date. the conference is open today and they have adopted an - today and they have adopted an agenda that is a critical piece of work, because this question that justice was outlining in his piece about loss and damage, about the damages that have been impacting on developing countries by rising temperatures, that is on the agenda and that is seen as a significant step. the world leaders are coming here, about 120 are coming in here,

but not this leaders of china, india, japan, australia, or canada. rishi sunak is coming here tomorrow and will make a statement and obviously making announcements. but we will be expecting things from him and other leaders to show they're committed to the battle against climate change and they're not too distracted with other issues in the world. ., . ., , , ., world. how much of this is about makin: world. how much of this is about making new _ world. how much of this is about making new promises _ world. how much of this is about making new promises on - world. how much of this is about making new promises on climate change, and how much about sort of making sure that people keep to the existing previous promises they have made and don't do any backsliding on those promises? yes. made and don't do any backsliding on those promises?— those promises? yes, rishi sunak us talkin: those promises? yes, rishi sunak us talking about — those promises? yes, rishi sunak us talking about backsliding _ those promises? yes, rishi sunak us talking about backsliding and - those promises? yes, rishi sunak us talking about backsliding and a - those promises? yes, rishi sunak us talking about backsliding and a lot i talking about backsliding and a lot of people are too, last year in glasgow, all the countries who attended, all agreed they would put new plans on the table by the end of this year to cut carbon and go beyond what they had promised and

only about 2k beyond what they had promised and only about 2a or 25 have done that. it is the same with many of the other promise, particularly on money, the hundred billion, that has not been delivered and it will be possibly next year before that happens. there is a lot of i suppose sarcastic views on the promises people have made. but the egypt government are keen to get some new stuff from the governments that come here and they will be pushing to get some new commitments. the criticism is alwa s of some new commitments. the criticism is always of the — some new commitments. the criticism is always of the cop _ some new commitments. the criticism is always of the cop process _ some new commitments. the criticism is always of the cop process is - some new commitments. the criticism is always of the cop process is it - is always of the cop process is it is always of the cop process is it is just a talking shop and doesn't achieve very much? isjust a talking shop and doesn't achieve very much?— achieve very much? yes, that's riaht, achieve very much? yes, that's right. some — achieve very much? yes, that's right, some have _ achieve very much? yes, that's right, some have said - achieve very much? yes, that's right, some have said it - achieve very much? yes, that's right, some have said it is - achieve very much? yes, that's right, some have said it is a - achieve very much? yes, that's i right, some have said it is a waste of time. but it is the only form or the only venue to allow this problem to be discussed. it works by

airport with the country's state broadcaster reporting that three people have died. the owners of the plane say 26 people have been rescued so far, the police chief said 43 people were on board. the aircraft, which had departed from dar es salaam, crashed into lake victoria due to storms and heavy rains, according to state media. our correspondent mayeni jones is monitoring all the developments. news of the crash started around 10am here. we know that 43 people were on board the plane, including 39 passengers. they're blaming bad weatherfor 39 passengers. they're blaming bad weather for the emergency landing. 0ne witness told state television they saw the aircraft aiming for the airport and missing and crash—landing into the lake a rescue operation is under way. pictures

from the scene show boats surrounding the aircraft. very little of it is visible and they're taking people out. and trying to rescue people who are on board. the authorities say they're in touch with the pilots on the aircraft, which suggests they are still alive, helping rescue workers. there has been a lot of reaction to the crash, the president has released a statement, sending her condolences to the families of those affected. saying that they will do everything they can to support the investigation and there have been statements echoing similar sentiments from the head of the the african union. precision airline, the aircraft that is involved, is the aircraft that is involved, is the biggest private aviation carrier in tanzania. it has been active

since 1993 and it is set up information desks in the area to provide help and information for any family members of those affected. the crucial us midterm elections, which will decide who controls congress, are just a couple of days away. president biden and former president 0bama have taken to the stage together at a campaign rally in pennsylvania. mr biden urged the cheering crowd in his home state to back the democrats' john fetterman for the senate. he said the elections would shape the country for decades to come. this isn't a referendum, this year, it's a choice, a choice between two vastly different visions of america, vastly different. maybe it's in our blood, butjohn and i believe that all... it's all about fighting for working and middle class people. the way i've said, from the beginning of my cam... my objective, when i ran for president, was to build an economy from the bottom up and the middle out.

it's a fundamental shift, compared to the 0zian, mega, maga, republican trickle down economics. booing. no, really. a fair economy that gives working people a fair shot. that's on the ballot. fundamental rights are on the ballot. truth and facts and logic and reason... applause. ..and basic decency are on the ballot. democracy itself is on the ballot. the stakes are high. speaking at a rally in pennsylvania, in support fo the republican candidate, donald trump stressed the importance of defeating the democrats on tuesday. there's only one choice to end this madness,

and it is indeed madness. if you support the decline and fall of america, then you must vote for the radical left democrats. if you want to stop the destruction of our country and save the american dream, then this tuesday, you must vote republican in a giant red wave. with me in the studio now is one of britain's leading us politcs experts, drjulie norman, a lecturer in politics and international relations at university college london — and a co—director of the centre on us politics there just looking at donald trump, how much of whether he runs again for the white house depends op how his nominated people in these elections, how successful they are?— how successful they are? trump has cast a long — how successful they are? trump has cast a long shadow— how successful they are? trump has cast a long shadow over _ how successful they are? trump has cast a long shadow over the - cast a long shadow over the midterms. many of us expect him to announce a candidacy, if his

candidates have not wanted to campaign with him. whatever happens in the midterms it will set biden's agenda and what will be realistic if he has a seek to seek the democratic nomination again or if it is a signalfor him to nomination again or if it is a signal for him to step aside. itruihat signal for him to step aside. what is at stake here _ signal for him to step aside. what is at stake here in _ signal for him to step aside. what is at stake here in terms - signal for him to step aside. what is at stake here in terms of- signal for him to step aside. what is at stake here in terms of house and the senate? talk us through what could happen and the implications. so we have the two houses in the congress that up for re—election. the house of representatives now democrats have a five—seat majority. it is very likely that the republicans will take back control of the house. the senate is neck and neck. now it is a 50/50 split and there are several key races that all are in a dead heat going into tuesday. that could go either direction. we expect one or both

houses will come under republican control. that means there will be a lot of gridlock on capitol hill and trying to put forward bills that biden with still veto. we will see talk of new investigations around hunter, biden, covid, things that republican want to get back at democrats' own investigation and a lot of agenda setting for 2024, try to get the issues that republicans want going to the presidential election on the forefront of voters' minds. hf election on the forefront of voters' minds. , ., , ., minds. if the democrats do lose control of— minds. if the democrats do lose control of one _ minds. if the democrats do lose control of one or _ minds. if the democrats do lose control of one or both _ minds. if the democrats do lose control of one or both of - minds. if the democrats do lose control of one or both of the - control of one or both of the houses, will the president be powerless, will the white house be paralysed? ihis powerless, will the white house be aral sed? , ., , powerless, will the white house be aral sed? , . , , . paralysed? his hands will be much more tied- — paralysed? his hands will be much more tied. we _ paralysed? his hands will be much more tied. we have _ paralysed? his hands will be much more tied. we have an _ paralysed? his hands will be much more tied. we have an executive | more tied. we have an executive action, where the president can take some steps that are beyond congress, but usually presidents try and use that only when necessary and i think biden will get a lot of push back

from congress if he uses it too much. a lot of republican manoeuvring will be trying to take control of budget priorities and push back at the policies the democrats have put in place and trying to rein that back in. it will be hard for bide on the avoid that. that is the problem with the constitution, in terms of separation of powers, you can end up with paralysis of power?— of powers, you can end up with paralysis of power? yes, some see that as an advantage, _ paralysis of power? yes, some see that as an advantage, that - paralysis of power? yes, some see that as an advantage, that the - that as an advantage, that the majority can't run away with power and there are systems of checks and balances. but it does mean a lot gets stuck and we have grid locked period. it gets stuck and we have grid locked eriod. , ., ,. ., ., period. it will be fascinating to see. period. it will be fascinating to see- thank _ period. it will be fascinating to see. thank you _ period. it will be fascinating to see. thank you for _ period. it will be fascinating to see. thank you for talks - period. it will be fascinating to see. thank you for talks us - period. it will be fascinating to - see. thank you for talks us through that. there will be an extra bank holiday
