Reform UK’s Richard Tice has been elected as the MP for Boston and Skegness.

Elsewhere in Lincolnshire, Labour candidate Hamish Falconer was elected the new MP for Lincoln, taking the seat from Conservative Karl McCartney.

Lincolnshire went into this election with seven Conservative MPs. It has emerged with six - and that includes the new seat of Rutland and Stamford.

Those Conservatives who did survive, including Sir John Hayes and Sir Edward Leigh, did so with vastly reduced majorities.

Meanwhile, Graham Stuart has been re-elected as Conservative MP for Beverley and Holderness following a recount.

The former energy minister won by just 124 votes, with 15,501, beating the Labour candidate Margaret Pinder into second place.

Mr Stuart – whose majority was almost 20,500 in 2019 – said it had been a "humbling night".

Elsewhere in East Yorkshire, Sir David Davis, the former Brexit Secretary, won in the newly formed constituency of Goole and Pocklington.

In Bridlington and the Wolds, another new constituency,Charlie Dewhirst was elected for the Conservatives with 14,846 votes.

In Hull, Labour's Emma Hardy won with a majority of nearly 9,000 in the redrawn constituency of Hull West and Haltemprice, and Karl Turner was re-elected as the MP for Hull East – where the turnout was just 41% – with an increased majority.

In the north of the city, Dame Diana Johnson won the redrawn seat of Hull North & Cottingham for Labour with 18,480 votes.

Labour gains in Lincoln, Great Grimsby & Cleethorpes and Scunthorpe were predicted as part of a landslide victory for Sir Keir Starmer’s party.

Former MPs Sir Nic Dakin and Melanie Onn will sit on the famous green benches once more after losing their Northern Lincolnshire seats to the Conservatives in 2019.

Reform UK’s win in Boston and Skegness looked far less certain.

Some activists even predicted a recount as the ballot papers began to stack up through the night.

In the end, Mr Tice secured a majority of more than 2,000 votes.

He says he’ll still talk about national issues, such as immigration, but insists he will knuckle down as a constituency MP and will represent this part of Lincolnshire to the best of his ability.

Meanwhile, some Tory MPs may feel lucky to still be in a job.

In Beverley and Holderness, Graham Stuart won his seat with a wafer thin majority of just 124 votes.

Whether they are newly elected, or have done the job before, the MPs heading to Westminster over the coming days carry high expectations from voters.

For two Labour candidates in northern Lincolnshire, this election was a chance to fight and take back the two seats they lost to the Conservatives back in 2019.

And they did just that.

Great Grimsby and Cleethorpes is made up of two former constituencies, one of them being Great Grimsby, which was a safe Labour seat for decades until the Conservatives took it during the "get Brexit done" campaign four and a half years ago.

This year, voters brought back Melanie Onn as their Labour MP for this new seat, but it was a hard fought race with Reform UK gaining momentum in second place.

In Scunthorpe, the Labour MP who lost his seat back in 2019 was also re-elected there.

Sir Nic Dakin told the BBC that Labour’s vote for change message had resonated with people living in and around the town, with the future of its steelworks at its heart.

Elsewhere, Brigg and Immingham and Doncaster East and the Isle of Axholme are two other new parliamentary seats created in northern Lincolnshire as part of the Boundary Commission review last year.

Former Cleethorpes MP, Martin Vickers, managed to stay in government after he was elected as the new Brigg and Immingham MP, but over in Doncaster East and the Isle of Axholme, Labour elbowed the Conservatives out of the picture and gained this seat for themselves.

The priority for the Labour party now, which has swept up most of the parliamentary seats in the area, is to prove to their voters that they can deliver on the pledges promised in their manifesto.

This shifting political tide south of the Humber estuary is reflective of the change that has come out of this general election as Sir Keir Starmer leads a new Labour government into Number 10.

It was a devastating night for the Conservatives across the country, losing seats in a number of areas.

But three of them stood strong in the East Riding of Yorkshire, appearing to buck the national trend.

Voters in the new seat of Bridlington and the Wolds elected Conservative candidate Charlie Dewhirst, a local councillor and senior adviser to the British Pig Industry.

In Goole and Pocklington, the area continues to be represented by the Conservatives, with Sir David Davis chosen as their new MP.

And it was a close call in Beverley and Holderness with the Conservative’s Graham Stuart hanging on by a thread with just 124 votes between him and the Labour candidate Margaret Pinder.

Elsewhere in the region, the city of Hull remains a Labour stronghold when it comes to its MPs. Two of the constituencies, Hull West & Haltemprice and Hull North & Cottingham saw changes with last year’s Boundary Commission review and they each widened out further into the East Riding of Yorkshire.

But still, both Labour candidates held their seats here, as did Karl Turner who was re-elected as the Labour MP in Hull East.

Reform UK came second in all three constituencies across Hull, and Labour will no doubt be asking how they can win the confidence of these voters who have clearly turned their backs on the main political parties.

These Labour MPs are entering Westminster with a new Labour government at the helm, but issues on their local doorstep such as poverty, housing and coping with the cost of living will still remain a challenge for them and the new Labour PM.

Labour candidate Hamish Falconer has been elected the new MP for Lincoln, taking the seat from Conservative Karl McCartney.

Speaking afterwards, Mr McCartney said he had fought a "positive campaign", but said that “divided parties do not win elections".

“You do take it personally, even though it’s out of your hands in many ways," he said.

"It is brutal… they say politics is the movies for ugly people, but you’ve got to take the rough with the smooth – I’ve had good nights and I’ve had bad nights."

Labour's Hamish Falconer is the new MP for Lincoln - the UK's oldest constituency.

Speaking to the BBC, Mr Falconer said he hadn't always wanted to be an MP, but was prompted to stand because he thought the country was "heading in the wrong direction".

Mr Falconer, who previously worked as a diplomat, said: "I thought when there are so many problems at home, I couldn’t continue going off overseas."

He said he was grateful to everyone who has supported him, adding: "I will do everything I can to live up to that trust."

Lincolnshire has two new MPs – Reform UK’s Richard Tice in Boston and Skegness and Labour’s Hamish Falconer in Lincoln.

Both men unseated Conservative MPs who were first elected to their seats back in 2010.

In the rest of the county, the Conservatives held on – but with vastly reduced majorities. For example, Dr Caroline Johnson held on to her seat in Sleaford and North Hykeham but had her majority cut from just over 32,500 to just under 7,000. Still, it’s not the collapse of the Lincolnshire blue wall some had feared – even if that’s not the case elsewhere in the country.

Even so, comparing vote shares with 2019 gives a stark picture, even accounting for the boundary changes.

In 2019 the Conservatives took 66.65% of votes – including Rutland which is now joined to Stamford.

Yesterday it was just 35% - almost half.

Where did those votes go? Well, Labour’s share only jumped from 20% in 2019 to 26% on Thursday.

The real story was that of Reform UK which took 22% of votes this time. That’s quite a story for a party that didn’t exist five years ago.

In a count that started at about 10.30 last night, it took a recount before Graham Stuart could be declared the MP for Beverley and Holderness, and retain the seat for the Conservatives.

In the end, his majority of almost 20,500 in 2019 was cut to just 124 votes by his challenger Margaret Pinder.

In his speech, Mr Stuart accepted it had been a poor showing for his party on the night, but ruled out running as leader.

The chairman of Reform UK, Richard Tice, has been elected as the MP for Boston and Skegness.

He won with 15,520 votes, beating Conservative Matt Warman into second place, with 13,510 votes.

The seat was previously regarded as one of safest Tory seats in the country.

In his acceptance speech, Mr Tice claimed that "a people's revolt was under way".

"I think this is just the beginning - we are just warming up," he said.

"This great country of ours can do so much better, and we intend to be a major part of that journey," he added.

Thanking his supporters, he pledged to work "tirelessly" to improve the lives of everyone in the constituency.

Labour's Emma Hardy has pledged to "bring all of our communities together" after winning the new constituency of Hull West and Haltemprice.

She won with 17,875 votes ahead of Reform UK candidate Julie Peck and Conservative Rachel Storer.

In her acceptance speech, she described it as a “huge honour” to represent the constituency and vowed to represent everyone, regardless of who they voted for.

“This election has been about change, she added.

Graham Stuart received 15,501 votes, beating Labour's Margaret Pinder into second place with 15,377 - a majority of only 124.

Reform UK's Andy Smith received 8,198 votes.

Graham Stuart has been re-elected as Conservative MP for Beverley and Holderness following a recount.

He won by just 124 votes.

There's no indication of when we're likely to get a result in the Beverley and Holderness constituency.

Currently there are a lot of tired and weary candidates and their supporters slumped in chairs, clinging on to their hot drinks as we hear the gentle, almost birdsong-like, sound of papers being counted.

And people begin to arrive for morning Aqua Fit.

Perhaps an indication of the time this could take is that East Riding Council staff have promised sausage sarnies for everyone here within half an hour.

The counting is over and the ballot boxes have been put away.

The Conservative Sir David Davis has been named the MP for the new Goole and Pocklington constituency and just in time for a new day to break in Goole.

Lincolnshire went into this election with seven Conservative MPs. It has emerged with six - and that includes the new seat of Rutland and Stamford.

We now have Reform UK in Boston and Skegness and Labour in Lincoln.

Those Conservatives that survived do so with vastly reduced majorities.

Conservative majorities in Gainsborough, Louth and Horncastle, South Holland and the Deepings, Sleaford and North Hykeham and Grantham and Bourne have been slashed dramatically.

For example, Sir John Hayes' majority in South Holland and The Deepings has gone from 30,838 to 6,856 (and Reform UK came second).

In Louth and Horncastle, Victoria Atkins' majority went from 18,868 to 5,506, in Sleaford and North Hykeham, Dr Caroline Johnson's majority went from 32,565 to 6,864 and in Grantham and Bourne Gareth Davies now has a majority of 4,496 - down from the 26,003 he had in his previous Grantham and Stamford constituency.

Alicia Kearns has won the new constituency of Rutland and Stamford for the Conservatives.

Linsey Smith

The MP for Goole and Pocklington, Sir David Davis, has said he will not take part in any Conservative leadership contest.

"I want to make sure my party finds the new ideas, finds the new solutions to these new difficult problems. I don't want to be tied up in front benches and cabinets and all that sort of administrative nonsense."
