LONDON, United Kingdom (AP) — An unrepentant Prime Minister Boris Johnson brushed off cries of “Resign!” and dared the political Opposition to try to topple him yesterday at a raucous session of parliament, a day after Britain’s highest court ruled he acted illegally in suspending the body ahead of the Brexit deadline.

Amid shouts, angry gestures and repeated cries of “Order!” in the House of Commons, Johnson emphatically defended his effort to withdraw Britain from the European Union by October 31, with or without a separation agreement with the EU.

“I say it is time to get Brexit done,” he declared, accusing his opponents of trying to frustrate the will of the people, who voted by 52 per cent-48 per cent for Brexit in 2016.

Johnson was greeted with applause from his own Conservative lawmakers and jeers from the Opposition side as he faced the Commons, hours after cutting short a trip to the United Nations in New York.

He flew home early after Britain’s Supreme Court unanimously ruled 11-0 Tuesday that his attempt to suspend parliament for five weeks had the effect of stymieing its scrutiny of the Government over Brexit. The court declared the suspension void.

The leader of the main Opposition Labour Party, Jeremy Corbyn, said the prime minister is not fit to govern and “should have done the honourable thing and resigned” after the ruling. He said Johnson “thinks he is above the law” and has shown “no shred of remorse or humility”.

“Have you no shame, Prime Minister?” asked Ian Blackford, the Scottish National Party’s leader in parliament. Labour Party lawmaker Jess Phillips urged Johnson “to act with some humility and contrition”.

Lawmakers accused him of showing disrespect for the rule of law and misleading Queen Elizabeth II when he asked for her permission to prorogue, or suspend, parliament. Over and over, they called on him to say he was sorry.

But Johnson ignored calls to step down or apologise, showing no sign of contrition. He has said he strongly disagrees with the Supreme Court ruling.

The prime minister said a new election is the only way to unblock Britain’s “paralysed parliament”.

“I think the people of this country have had enough of it — this parliament must either stand aside and let this Government get Brexit done, or bring a vote of confidence and finally face the day of reckoning with the voters,” he said.

A no-confidence vote could bring down his Government and lead to a new election.
