Jeremy Corbyn bottles backing Boris Johnson’s bid to hold an early general election on December 12

Jeremy Corbyn will tonight scupper Boris Johnson’s hopes of holding a general election on December 12 after the shadow cabinet agreed Labour MPs should abstain on a crunch vote.

Mr Johnson will this evening ask MPs to back holding a pre-Christmas snap poll and under the terms of the Fixed-term Parliaments Act 2011 he will need the support of two-thirds of the House of Commons to get his wish. 

But Mr Corbyn and his top team decided at a special shadow cabinet meeting at lunchtime that Labour MPs will be instructed to abstain on the vote. 

That means the Prime Minister will almost certainly fail to secure the support of the 434 MPs he needs to trigger an election. 

The decision to abstain will prompt a furious reaction from Mr Corbyn’s political opponents, with the Tories, Liberal Democrats and SNP all now united in their desire for an election to be held in December. 

However, it does mean that Mr Corbyn will avoid a damaging rebellion on his own backbenches. 

Pro-Remain Labour MPs had made clear they will not vote for an election to take place before Brexit has been resolved. 

They are concerned that if Labour fights an election with its existing policy of staying neutral on Brexit then the party will be decimated at the ballot box.   

Now that Mr Corbyn has opted to block this evening’s vote, Downing Street is now expected to pivot to pursuing a Plan B.

The Liberal Democrats and SNP have combined forces to bring forward a plan which would ask MPs to vote in the coming days for a draft law calling for an election to be held on December 9. 

Number 10 views the plan as a good fallback option and sources suggested that the government will bring forward its own version of the Lib Dem/SNP bill if the PM fails tonight. 

So even if Mr Corbyn does block an election this evening it is possible that the Tories, Lib Dems and SNP could have forced a pre-Christmas poll against his wishes by the end of the week.  

Westminster is now focused on whether there should be an election after the European Union granted the UK a three month Brexit delay. 

The chances of MPs using that time to pass Mr Johnson’s Brexit deal appear slim with all eyes now on going to the country early. 

The Tories believe that they can win the next election by pledging to ‘get Brexit done’. If Mr Johnson won a majority he would then rush his divorce deal through Parliament. 

The pro-Remain Lib Dems and SNP also believe they can perform strongly at a snap poll as they seek to capitalise on pro-EU support across the country. 

But many senior Labour figures believe the party is ill-prepared for a pre-Brexit election. 

A number of prominent members of the shadow cabinet including Emily Thornberry and Sir Keir Starmer are pushing Mr Corbyn to back a second referendum instead so that the sting can be taken out of the Brexit question before voters are asked to elect a new set of MPs.

Many recent opinion polls have Labour trailing the Tories by double digits and the party’s MPs cite those numbers as evidence that an election must be avoided. 

One set out their opposition in colourful terms to the Politics Home website as they said: ‘I won’t be voting for a general election come hell or high water. They can go f*** themselves. Brexit must be sorted.

‘As for winning, you’ve got to be pretty dim to ask for the chequered flag when you’re stuck at the back of the grid.’

The prospect of the Lib Dems and SNP working with the Tories to force an early election sparked anger from Labour frontbenchers. 

John McDonnell, the shadow chancellor, tweeted: ‘Looks like the Lib Dem and Tory pact of 2010 is being re-established. 

‘They are back together, selling out the People’s Vote campaign and the cross party campaign to prevent a no deal. 

‘The Lib Dems will stop at nothing to get their ministerial cars back.’   

Last night Labour frontbencher Lucy Powell told the Westminster Hour that an ‘election soon is now both inevitable and necessary’.

She said: ‘Parliament is in a deadlock and we need to break that deadlock somehow, even if Brexit is done. 

‘The issue is the terms of that election, the when and how of that election. I think what we’ve seen from the Liberal Democrats and the SNP is trying to shape the terms of that election in a way that would favour them the most, it’s pure playing of politics.’
