While we're getting a flurry of updates from across London's constituencies, let's take a look now at how voter turnout fared in the capital this year in comparison to 2021.

There was a slight decrease in this year's London mayoral election, which earlier led to widespread speculation that the election could be much tighter than the polls had predicted.

Voter turnout was 40.5% this week, down 1.5% overall from 2021.

With five out of 14 results already in, those speculations appear to be wide of the mark.

In the areas that we already have final counts for, not only is Khan ahead, he's actually increased his share of the vote.

We're not expecting a final result until 17:00 BST, but Labour sources are already telling the BBC they think they've won it already.

First outer borough result suggests ULEZ not a big factor on electionpublished at 14:11 British Summer Time 4 May

The South West London result is the first declaration from an outer London constituency.

It is a constituency in which the Conservatives were ahead last time but Labour have won this time.

It looks as though outer London is swinging to Labour in much the same way as inner London, and that the ULEZ row is not going to have a significant impact on the result of the mayoral election.

Sadiq Khan has just won another area of London and it looks like Labour's mayor could be on his way to re-election.

He won in South West London by 77,011 votes to Tory challenger Susan Hall's 68,856 votes.

That's a swing to Labour of 2.6 percentage points - and the second part of London so far today that has gone from backing the Tories in 2021 to Labour in 2024.

As these results come in, Labour sources say that Sadiq Khan has won London.

In another result from the 14 constituencies in London's mayoral race, Sadiq Khan has held the North East.

The swing to Labour from the Conservatives was 6.9%.

Khan received 127,455 votes - or 61.7% - while Conservative Susan Hall received 34,099 - 16.5%.

That's now a third London mayoral constituency declaration, albeit again from the inner part of the city.

It shows a 5% swing from Conservative to Labour in a constituency where the Conservatives were ahead in 2021 - but has now been won by Sadiq Khan.

We again have a further indication that Khan should be re-elected as mayor of London.

Another vote in one of London's mayoral regions has gone Sadiq Khan's way.

The Labour mayor has beaten Tory Susan Hall by 54,481 to 43,405 in West Central.

It suggests Khan is on track to be re-elected.

'Knife edge' result in West Midlandspublished at 13:32 British Summer Time 4 May

Hello from me in Birmingham, where it looks like all the counting has already finished.

There are about half a dozen count centres around the region and there won’t be a formal result until they’re all done.

Both the Conservatives and Labour claim the result here is "on a knife edge" but it’s Labour who are sounding more pessimistic.

A Conservative win here - a victory for Andy Street - would be a helpful psychological fillip for Rishi Sunak.

We're expecting a result at 14:30. Stay tuned .

Heading back to the ICC in Birmingham, where it's a tense atmosphere as votes for the West Midlands mayoral race are being counted.

Labour and the Conservatives both think this contest is on a knife edge.

Similar counts are taking place in the other six council areas that make up the West Midlands Combined Authority, adding to the drama as bits of information and rumour flow through to us here.

Conservative candidate Andy Street hopes his own personal brand is distinct enough from the national party and that enough people who are fed up with the government have lent him their vote.

The Labour campaign are concerned that support for pro-Palestinian independent Ahkmed Yakoob could cost them dearly.

We don’t know yet if he’s been supported by disaffected Labour voters or people who wouldn’t have voted at all if he wasn’t standing.

There are very nervous faces all round.

Back over to Sheffield now, where we've just been hearing from Oliver Coppard following his re-election as mayor of South Yorkshire.

In his victory speech, Coppard directed criticism at the government for its "failure to level up our country, to do what is right for the whole of our country".

“I cannot promise to answer every question we face, to immediately overcome the many problems that we’re up against in our communities, across 14 years of Tory governments and 40 years of industrial decline," he says.

“But I can promise – indeed, I do promise – never to neglect that challenge. And to always think first of those who all too often come last.”

He says he would use his renewed mandate to "pursue the change we so desperately need across South Yorkshire" and give everyone living there the chance to "stay near and go far".

Back over to Liverpool, where we've just heard from Mayor Steve Rotheram, who uses the first part of his victory speech to take aim at the government's new ID requirements at polling stations.

He says he understands the disappointment of people who were unable to vote in this election because of the "regressive" law.

Rotheram says Liverpool's voters have "hollered at the top of their voices" to tell the government "enough is enough", before setting out his hopes for more devolved powers under a Labour government.

He continues: "The road to Downing Street runs through transformative Labour administrations in local and regional government.

"With Labour in Westminster, we will get to see what real devolution is like, not the limited decentralisation we are seeing now."

He ends by accusing Prime Minister Rishi Sunak of "squatting in Downing Street" and tells him now is the time to call a general election.

As we've just heard, Labour's Oliver Coppard has comfortably been re-elected for a second term as mayor of South Yorkshire. Here's a full breakdown of the results:

• Labour – 138,611
• Conservatives – 44,945
• Green – 37,142
• Liberal Democrats – 31,002
• SDP – 20,835

We'll be hearing from the second-term mayor shortly, so stick with us as we bring you some of what's said in the next little bit.

Voters say 'I do' to Labour mayorpublished at 12:52 British Summer Time 4 May

Political Editor, BBC Yorkshire, reporting from Sheffield

There were two weddings in the Town Hall today – in the room next to where the ballots were being counted.

Voters have pretty emphatically said "I do" to Labour Mayor Oliver Coppard.

He’s been the mayor for the last two years but faced an early election because the South Yorkshire Mayor now takes on the police commissioner's job.

The win was expected, but the real analysis of the results for Labour will be in those places that voted Conservative for the first time in the 2019 Westminster elections.

Labour’s figures suggest they’ve done well there as well – boosting their hopes of taking them back at the next general election.

In London, Labour are feeling confident as first results come inpublished at 12:46 British Summer Time 4 May

Leaving Liverpool for a moment, the first results are in from London - and they’re good news for Labour.

There has been a swing to Sadiq Khan in the two areas which have declared.

In Merton and Wandsworth, there was a 5.1% swing to Labour from the Conservatives. In Greenwich and Lewisham, there was a 4.5% swing to Labour.

Remember; the Tories needed a swing to take this race. Labour are feeling confident - and these results show why.

As was expected, Labour's Steve Rotheram won easily in Liverpool to secure a third term in office, beating his nearest rival by more than 156,000 votes and increasing his vote share by 9.7 points.

Here is a full breakdown of the result:

• Labour - 183,932
• Conservative - 27,708
• Green - 26,417
• Liberal Democrat - 21,366
• Independent - 11,032

We're just about to hear from him now and we'll be bringing you some lines from his victory speech shortly.

While we're waiting for the results in Liverpool and South Yorkshire, we've just had one of the remaining council results.

The Conservatives have kept control of Epping Forest in Essex, despite losing three councillors amid a strong vote for local independents.

The area is a Tory stronghold and despite some losses, the party now has one more councillor than needed for an overall majority.

The Liberal Democrats and Labour each picked up one councillor, while the Greens lose two.

South Yorkshire should be comfortable Labour winpublished at 12:24 British Summer Time 4 May

Lucy Ashton
BBC political reporter in Sheffield

It should be a comfortable win for Labour in South Yorkshire, after they won last time around with 43% of the vote.

For the first time, South Yorkshire’s mayor will also take on the role of the police and crime commissioner.

Labour’s Oliver Coppard was elected as mayor in 2022 and should have served a four-year term, but the election was brought forward after the government merged the roles of mayor and PCC.

It is likely the new mayor will appoint a deputy to be police and crime commissioner, as other regional mayors have done.
