It was a wafer-thin victory, but a huge win.

The symbolism of Labour taking the West Midlands mayor, a jewel in the Tory crown, could be felt in the room as Labour activists gathered in Birmingham to celebrate the win with their new mayor Richard Parker and Labour leader Sir Keir Starmer.

There are moments on election journeys when the momentum shifts – and this win felt like one of them.

“We humbly asked [the voters] to put their trust and confidence in a changed Labour Party and they did. And that is a significant piece of political history that we’ve made here today,” said Sir Keir at his victory rally.

“So the message out of these elections, the last now the last stop before we go into that general election, is that the country wants change.

“I hope the prime minister is listening and gives the opportunity to the country to vote as a whole in a general election as soon as possible.”

This win gave them the boost that was missing when they won the Blackpool South by-election on a massive 26-point swing, but then failed to pick up the hundreds of council seats they were chasing.

This win, on just 1,508 votes or 0.25 per cent of the vote, was a body blow for a Conservative party that believed they could just about cling on. Ben Houchen, the Tees Valley mayor, is now the last Tory standing.

For Labour, then a moment to bookmark.

Just as Boris Johnson’s Hartlepool by-election win in 2021 was a low point for Sir Keir – he told me this week that he considered resigning over the loss because he thought it showed he was the barrier to Labour’s recovery – this too will feel devastating not just for Andy Street but for the PM too.

Labour has beaten him in a street fight. He’s bloodied with Sir Keir now emboldened.

“This was the one result we really needed,” said one senior Labour figure. “It’s been our top focus for the past week and symbolically a very important win.”

And Labour needed the boost, because, as Professor Michael Thrasher pointed out in his Sky News’ national vote share projection calculated from the local election results, Sir Keir was not picking up the sort of vote share that Tony Blair was winning in the run-up to the 1997 Labour landslide.

His latest calculation of a 35% vote share for Labour and 26% for the Tories, put Sir Keir winning a general election but short of a majority.

What the West Midlands mayoral win did for Sir Keir was to give him a clear narrative that he is coming for the Tories and will do what he needs to take them down.

It raises inevitable questions about what is next for Rishi Sunak. The prime minister had nowhere to go today, not one win to celebrate. The worst performance in council elections in 40 years, was already pretty much as bad as it gets before the loss of Andy Street. The former Conservative mayor was magnanimous towards the prime minister, saying the loss was his alone.

But colleagues will not be so generous. One former cabinet minister said this loss was “devastating”. “We’re done and there’s no appetite to move against him,” said the senior MP. Many Tories tell me they are now resigned to defeat and believe Mr Sunak and his team needed to own it, rather than the rest of the party.

The coming days might be bumpy, the mood will be stony. But Tories tell me not much will actually change for them.

For Sir Keir, he now needs to sell not the changed Labour Party, but his vision for changing the country. The West Mids mayor’s win was dazzling, but it could have so easily gone the other way. And as Mr Sunak fights to survive, Labour still has to fight hard to win.

Boris Johnson has paid tribute to the villagers who Sky News revealed turned him away from a polling station when he tried to vote without a valid photo ID – under rules he introduced.

The former prime minister said he attempted to cast his ballot using a magazine sleeve with his name and address on as proof but was prevented from doing so.

The requirement to provide photo ID was introduced by Mr Johnson during his time in Downing Street as part of the Elections Act 2022.

The move was controversial over fears it would bar people from voting, particularly among disadvantaged groups.

Mr Johnson had been seeking to vote in South Oxfordshire, where a police and crime commissioner for Thames Valley was being elected.

Writing in his Daily Mail column, he said: “I want to pay a particular tribute to the three villagers who on Thursday rightly turned me away when I appeared in the polling station with nothing to prove my identity except the sleeve of my copy of Prospect magazine, on which my name and address had been printed.

“I showed it to them and they looked very dubious… within minutes I was back with my driving licence and voted Tory.”

Thursday’s election is the first time many voters in England and Wales have had to present ID to vote under provisions first rolled out at last year’s local elections.

As well as driving licences, other acceptable forms of ID include passports, proof of age cards, blue badges, and some concessionary travel cards.

The government has also said it intends to make veterans’ ID cards a valid form of voter identification after former service personnel were turned away.

Veterans’ minister Johnny Mercer apologised to those who had been unable to use the document to vote, vowing to “do all I can” to have it added to the list of valid identification.

Labour said the government has had years to ensure the card was included, having begun rolling out the scheme in 2019.
