'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 push for an election comes as the government said it would abandon its attempt to pass its Brexit bill, for the time being.
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.'
