Boris Johnson will try for a fourth time to secure an early general election, after MPs rejected his plan.
The prime minister will publish a bill proposing a poll on 12 December that would only need a simple majority to succeed – not two-thirds as required in previous attempts. However, he would still need votes from smaller parties for it to pass.
Mr Johnson said Parliament was “dysfunctional” but Labour said the prime minister could not be trusted.
The Commons backed the government’s election motion by 299 to 70 on Monday – well short of the two-thirds majority needed under the Fixed-term Parliaments Act.
All Conservative MPs backed the motion, but the vast majority of Labour MPs abstained, along with the SNP and DUP. All but one MP from the Liberal Democrats voted against it.
The vote came after Mr Johnson officially accepted the EU’s offer of an extension to the Brexit deadline to 31 January.
This means the UK will not now leave the EU on Thursday – 31 October – a promise at the heart of Mr Johnson’s campaign to become prime minister.
In a letter to EU officials, Mr Johnson said the further delay – which he insists was forced upon him by Parliament – was “unwanted”.
Mr Johnson said he would persist with his efforts to get an early election, telling MPs that “one way or another” the current deadlock had to be broken.
Jacob Rees-Mogg, Leader of the House of Commons, said the government wanted MPs to debate all stages of a bill for a 12 December election on Tuesday.
Usually a bill is debated over the course of several days, but Mr Rees-Mogg said the legislation would be “extremely short, simple, and limited in scope”.
The bill would also have to pass through the House of Lords before it could come into effect.
Mr Rees-Mogg added that the government would not bring its Withdrawal Agreement Bill back to MPs for scrutiny, as would be required for Mr Johnson’s Brexit deal to become law.
