British Prime Minister Boris Johnson could suspend parliament again even if the Supreme Court rules that his original suspension, or prorogation, was unlawful, a court document tweeted by an opposition lawyer showed on Thursday.

Axar.az reports citing Reuters that the document, submitted to the court by Johnson’s lawyers, was disclosed as Britain’s top judicial body was hearing a third and final day of legal arguments on whether the prime minister’s decision to suspend parliament from Sept. 10 to Oct. 14 was lawful.

On Tuesday, one of Johnson’s lawyers had told the court that if the prime minister lost the case, he could recall parliament earlier than scheduled.

“The (submissions from Johnson’s lawyers) contemplate a world where the Supreme Court rules this prorogation unlawful and the government is plainly contemplating, in that world, continuing the prorogation until October 14,” Maugham said.

Major’s years in office between 1990 and 1997 were marked by bitter divisions and conflict within his party and government over Britain’s relations with the EU. He described some of his own anti-EU cabinet members as “bastards”.

The Conservatives are more divided than ever over the EU issue. Using his authority as an elder statesman, Major has said Britain should remain in the EU, and has warned that a no-deal Brexit would be disastrous for the nation.
