The government is to ask MPs to agree to a snap election for a second time, in what could be one of Parliament's last acts before being suspended, APA reports citing BBC.
No 10 has billed Monday's vote as Labour's "last chance" to secure an early general election.
But the government is expected to be defeated, with opposition parties wanting their law aimed at avoiding no-deal to be implemented first.
Boris Johnson is also due to meet Irish Prime Minister Leo Varadkar in Dublin.
The prime minister first called for a snap election after MPs - including rebel Tories - voted in favour of a bill requiring him to seek an extension to the Brexit deadline of 31 October if a deal is not reached before 19 October.
That bill is set to gain royal assent and become law on Monday, but has been criticised by ministers as "lousy" and weakening the government's negotiating position with Brussels.
Downing Street said Monday's vote, which comes ahead of this week's shutdown of Parliament, was Labour's last chance to secure an early election and have the chance to win its own mandate from the public to delay Brexit.
The motion, which requires the support of two-thirds of MPs, was defeated last week and is expected to fail again.
