What no one saw coming quickly triggered a wave of heated reactions online, with supporters calling it a “game-changing shift,” while critics raised uncomfortable questions about what this vote is really saying beneath the surface. Within minutes of the result being announced, social media platforms were flooded with intense debate, with both sides insisting there is a deeper meaning being deliberately overlooked.

Andy Burnham is poised to storm Downing Street after a stunning win in the Makerfield by-election.

The Greater Manchester Mayor secured a majority of 9,000 votes over Reform in a result that sparked tears of joy from Labour Left-wingers – who want far more extreme tax and spend policies.

Mr Burnham immediately made clear he will try to replace Keir Starmer as PM, insisting he is heading for the ‘heart’ of politics and the party has a ‘final chance to change’.

The scale of the victory heaps massive pressure on Sir Keir – who is still vowing to fight any challenge – to allow a ‘coronation’ that could take place within days.

It was achieved after a wave of previously loyal Labour big beasts and celebrity backers flooded the constituency yesterday.

Sir Keir posted on X congratulating Mr Burnham this morning, pointedly praising ‘Labour’s campaign’.

His dwindling band of allies are continuing to warn of ‘chaos’ and an early general election if there is a coup.

Ex-minister Baroness Harman – who was appointed as an adviser by Sir Keir just last month – has called for a ‘process’ where MPs are given the choice of who is going to be PM. She argued that a woman should also be on the ballot.

Labour backbenchers who previously supported Sir Keir staying are now privately saying he needs to quit.

One told the Daily Mail: ‘Andy Burnham has exceeded all expectations and I’m absolutely sure that there’ll be an orderly transition of leadership now. Keir would be unwise to try and stop it.’

Nigel Farage admitted he was ‘disappointed’ by the result, acknowledging Reform had struggled to counter the message of ‘vote Burnham, get Starmer out’.

He blamed Restore splitting the Right for Reform getting 16,000 votes instead of the 18,000 he had expected. In a direct message to those who supported Rupert Lowe’s outfit, Mr Farage said: ‘What do you want? We are the challenger party to the Left in this country.’

On a potentially pivotal day for Britain’s future:

  • Both Mr Burnham and Sir Keir are set to make public appearances later with events moving quickly;
  • Interest rates on Government debt ticked up slightly this morning, although similar moves have been seen in other European bond markets amid uncertainty over oil prices;
  • The danger of a lurch to the Left was underlined as official figures showed public sector borrowing surging to a record level for May, outside of the Covid peak. Interest rates on the country’s debt mountain and the Government’s spending splurge were behind the spike;
  • In a separate by-election contest in Aberdeen South, the Tories secured a huge win over the SNP after successfully turning the race into a referendum on oil and gas drilling in the North Sea;
  • The SNP did hold Arbroath and Broughty Ferry in a third by-election result of the night.

Andy Burnham has begun his march on Westminster – and potentially to Downing Street – after winning the Makerfield by-election
