Newly elected Labour MP for Barnsley South, Stephanie Peacock, says the victory is a "very clear message of confidence" from voters.

Speaking after the announcement, she said: "They have chosen hope over division, they have chosen a changed Labour party, back in the service of working people.

"A Labour government that has pledged to deliver economic stability, a government for those who haven't been able to access the treatment they need, for those who have lost faith in our justice system, rest assured, we will rebuild our public services.

"And for the thousands of miners, who powered our country, we will finally deliver justice for the mineworkers pension scheme."

Labour's Dan Jarvis, the former Mayor of South Yorkshire, is celebrating his victory in Barnsley North after suggestions the seat would be won by Reform UK.

In a post on X, external, Mr Jarvis says 'reports of my demise had been greatly exaggerated'.

In an interview with BBC Radio Sheffield, he added: "I think some people had already written my political obituary but I'm delighted that we've secured a good, big win.

"I've doubled my majority and I'm immensely proud to be elected to represent the people of Barnsley North."

We've looked at the smallest majorities, now for the biggest.

As explained earlier the redrawing of constituency boundaries in 2023 has resulted in a recalculation of the majorities - with the figures below reflecting the majorities that would have been achieved in 2019 based on the 2024 boundaries.

The largest majorities in Yorkshire are:

• Wetherby and Easingwold - 27,164
• Bradford West - 27,019
• Richmond and Northallerton - 24,331
• Thirsk and Malton - 23,337
• Skipton and Ripon - 22,517

In total, 132 MPs chose not to stand again at the general election, including six from Yorkshire.

Conservatives Robert Goodwill (Scarborough and Whitby) and Craig Whittaker (Calder Valley) chose not to seek re-election this time, as did former Labour MPs Paul Blomfield (Sheffield Central), Holly Lynch (Halifax), Barry Sheerman (Huddersfield) and Rosie Winterton (Doncaster Central).

Mr Sheerman, who announced his plan to step down in 2021, was first elected as an MP for Huddersfield East in 1979 before representing the Huddersfield constituency from 1983.

The 84-year-old described his time in parliament as "the honour of my life" but said he was looking forward to spending more time with his family.

Dan Jarvis has been elected as MP for Barnsley North.

Mr Jarvis secured 18,610 votes followed by Robert Lomas, who received 10,799.

Mr Lomas had initially been a candidate for Reform UK but the party withdrew support over offensive comments.

The Conservatives came third with 3,083 votes while the Greens came fourth with 1,805 votes.

Nick Fletcher, the Conservative candidate for Doncaster East and the Isle of Axholme says he is hopeful of being elected despite it being a "tough night" for his party.

"If these polls are right, we've got five years of decline and hopefully people will see that and then we can have a strong Conservative government and rectify their errors," he said.

"If we can come back then, then hopefully we can set the country back to where it needs to be."

South Yorkshire was full of surprises in 2019, but where will the interest be this year?

I'm tipping these three seats as ones to watch.

Sheffield Hallam – the smallest majority in South Yorkshire and one of the few constituencies nationwide which is head-to-head between Labour and the Lib Dems. Labour won it in 2019 with a slim majority of 712 and it’s number three on the Lib Dems’ target list.

Rother Valley – the constituency was Labour for over 100 years before turning blue in 2019. It’s the epitome of a red wall seat, where mining communities voted Conservative for the first time in generations.

Barnsley South – This was one of the first places Nigel Farage visited after announcing his return as Reform UK leader. He said he doesn’t expect to win but wants to come a strong second to build the groundwork for the next general election.

In Rotherham, there are three seats up for grabs for Rother Valley, Rotherham Central and Rawmarsh and Conisbrough.

The counting hall is hot - packed with volunteers furiously flicking through papers.

We've just caught up with Reform UK candidate Tony Harrison, who's standing in the Rother Valley seat. He's seen the exit poll for Barnsley North and South which suggest a Reform UK win.

"It's looking quite positive," he says.

When asked why he thinks that is, he adds: "Quite strange times, I think it all stems from Brexit. There was a high Brexit vote in Barnsley."

Does he think he could win his seat from the Conservatives in Rother Valley?

"Yeah, never say never. Think it'll be a tight-run thing. The Conservative candidate seems to be doing better than expected, certainly not an easy night for Labour. I might come a close second maybe, or even maybe even take the seat. More likely to be a close second."

Labour councillor Chris Read, leader of Rotherham Council, has said not to judge the exit polls "too soon", and wants to wait for "the real votes" to be counted.

"We did of course have a big Leave vote [in Rotherham], we had a big Ukip group on the council before, so in some ways perhaps not too much of a surprise Reform are doing well. I don't think they're doing well enough to challenge the two big parties for seats here in Rotherham," he adds.

Perhaps the biggest surprise of this general election is that neither Rishi Sunak nor Keir Starmer have been seen in South Yorkshire during the campaign.

Instead of visiting the so-called "red wall" seats which made the headlines in 2019, both party leaders have instead concentrated on safe Conservative seats in other parts of the country.

Liberal Democrat Leader Ed Davey bounced through SheffieldHallam, where the party is going head-to-head with Labour.

But even that visit – spent making insect houses – seemed subdued for Mr Davey, who has spent his campaign bungee jumping, riding fairground rides and performing water stunts.

Reform UK leader Nigel Farage had the most high profile visit, riding through Barnsley on an open top bus, glad-handing shoppers and addressing crowds with a microphone, though his foray was marred when a member of the public hurled a number of items towards him.

Our reporter at the Barnsley North count says a declaration is expected within the next 10 minutes.

The counting here in Sheffield is being split at the English Institute of Sport between the athletics track and the netball hall.

There's only 40 steps between them, with constituencies Penistone & Stocksbridge and Brightside & Hillsborough being counted in the smaller room.

Conservative Miriam Cates, incumbent MP for Penistone & Stocksbridge, has come prepared for a long night it seems, bringing her own camping chair.

Her team's snacks of choice appear to be Haribo sweets, cupcakes and millionaire shortbread biscuits, but she's spent most of her time on her phone or speaking to colleagues to worry about them.

The TV behind her has just shown the first result to come in - a Labour win in Sunderland South

The cupcakes have just been opened.

Labour's Sheffield South East candidate Clive Betts says he believes the surge in support for Reform UK is down to people people the north being fed up with decades of decline.

"People get very frustrated at what they see is years and years of failure to regenerate these areas and bring decent jobs to them," he said.

"That's going to be a massive challenge for the new government to do what the Tories failed to do and that's to genuinely put some proper resources, proper skills, proper infrastructure into the poorest areas to give those areas a chance for renewal for the people there."

Meanwhile, on his own party's precited victory he said: "I think this will be the first step on a very difficult journey.

"We have been honest throughout this election there are no easy fixes, the Tories have run public services into the ground, people are desperately hard up with their own personal finances and it's going to take a long time to repair the damage. We can't do it overnight but we can begin to move in the right direction."

The leader of Barnsley Council, Sir Steve Houghton, says he doesn't believe Labour will lose Barnsley North and Barnsley South to Reform UK, whatever the exit polls say.

"These are very abstract calculations, not necessarily based on an exit poll in Barnsley but on what's going on elsewhere in the country, and then they transpose that onto Barnsley and say 'look at this!'

"There's no doubt Reform will do well, but equally I'm confident we'll retain two Labour MPs in Barnsley."

Of the 45 seats contested in 2019 across North, South and West Yorkshire, seven switched hands, and all seven turned from red to blue.

The Conservatives took Don Valley, Penistone and Stocksbridge, Rother Valley, Keighley, Colne Valley, Dewsbury and Wakefield five years ago as Labour's so-called "red wall" crumbled.

On a night of big wins for the Conservatives, Alex Stafford (pictured above) became the first Tory MP for Rother Valley since it was created in 1918 while Nick Fletcher ended almost 100-years of Labour dominance in Don Valley.

Since then Wakefield has turned red again, with Simon Lightwood winning the seat following a by-election in June 2022 after previous incumbent Imran Ahmad-Khan was convicted and jailed for sexual assault.

The UK exit poll predicts that Reform UK may win seats in our region. Namely:

Barnsley South 49% of the vote – Labour 39%

Barnsley North 48% of the vote – Labour 37%

If these results were to come true the votes in Barnsley would be the biggest vote share for Reform in the country – out polling Nigel Farage in Clacton.

The party is running Labour close in the following seats

Pontefract, Castleford and Normanton – Labour 41% Reform 36%

Rother Valley – Labour 38% Reform 35%

Doncaster East and Isle of Axholme – Labour 34% Reform 33%

Large metal trollies have arrived carrying the first ballot boxes here at the English Institute of Sport in Sheffield.

There's whispers on the press bench here about the Liberal Democrats having a very high chance of taking Sheffield Hallam - which is currently under Labour control.

People on the counting floor have been gathering around TVs and having hushed conversations with each other. It feels like this is it. Counting is to begin shortly.

Lots of people on the floor are checking their phones again and again. I hope someone remembered to bring a charger.
