Britain’s opposition parties gathered on Monday to explore ways to force Prime Minister Boris Johnson to abide by a legislation that blocks a no-deal Brexit.

Axar.az reports citing Turkish media.

Gathering at the Labour Party leader Jeremy Corbyn’s office, leaders of the opposition parties discussed how to ramp up the pressure on Johnson, who has repeatedly said he would not ask for an extension beyond Oct. 31 and the U.K. would leave the EU on that date.

The meeting saw the attendance of Scottish National Party’s leader in Westminster Ian Blackford and Lib Dems leader Jo Swinson as well as representatives from other opposition parties and independent MPs.

During the meeting, the parties discussed a no-confidence vote to bring down Johnson’s government if he denies to obey the law, also known as the Benn act, which blocks a no-deal exit from the bloc at the end of October.

They remained in agreement to look into all options to stop the country’s departure without a deal, including a national unity government to succeed Johnson when and if he fails to find majority for confidence vote.

The numbers in the House of Commons do not look in favor of the prime minister at the moment, especially after the removal of party whip from 21 MPs earlier this month as they voiced and voted different Brexit opinions than Johnson’s.

The opposition parties however have failed to agree on who should lead such a national unity government, which would first block the no-deal exit by securing an extension to the current Brexit deadline of Oct. 31 and then initiate a general election.

If Boris Johnson loses such a no confidence vote and cannot secure enough votes in 14 days following the vote, the Queen will ask any other MPs in the House of Commons to form a government which could receive confidence of the MPs.
