The British Prime Minister Boris Johnson has told the UK parliament it is 'paralysed'.
He addressed MPs following a British Supreme Court ruling on Tuesday, which found that his earlier suspension of the parliament was unlawful.
In their unanimous decision, the 11 judges found that prorogation was "void and of no effect".
Their judgement stated they had been presented with no reasons - “let alone a good reason” - for the five-week suspension of parliament in the weeks leading up to the October 31st Brexit deadline.
Mr Johnson was heckled at the beginning of his speech in the House of Commons on Wednesday evening, with one MP shouting that he should be in jail.
He challenged opposition parties to call a confidence vote that could trigger a general election there.
"They have until the house rises today to table a motion of no confidence in the government - come on, come on, come on then!
"And we can have that vote tomorrow," he said.
"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".
UK Labour leader Jeremy Corbyn responded that Mr Johnson's statement was 'null, and should be quashed' - likening it to his decision to suspend parliament.
"He says he wants a general election, I want a general election - it's very simple: if you want an election, get an extension and let’s have an election", Mr Corbyn added.
He also repeated his demand for Mr Johnson to resign following the Supreme Court ruling: "For the good of this country he should go."
The leader of the Liberal Democrats Jo Swinson said Mr Johnson needs to apologise.
"Surely the prime minister can have the humility to say sorry for misleading the queen, misleading the country and illegally shutting down our democracy".
The SNP's Westminster leader Ian Blackford told MPs his party "fully supports" stopping a no-deal Brexit as their "priority", as he also called for Mr Johnson to resign.
He also floated the possibility of an "interim" prime minister seeking an Article 50 extension from the EU "to take back control and to protect our economy from the cliff edge".
Politicians rushed back to London for the sitting, where the agenda gave MPs an opportunity to question the British government on issues such as Brexit and other topical issues.
Shortly after the sitting opened, the UK's Attorney-General Geoffrey Cox defended advising Mr Johnson that suspending parliament for five weeks was lawful.
The SNP's Joanna Cherry - who took one of the cases that led to the Supreme Court hearing - demanded Mr Cox disclose the full details of the guidance he gave.
Mr Cox told MPs he would consider releasing the full advice.
He suggested: "The government accepts the judgement, and accepts that it lost the case.
"At all times the government acted in good faith, and in the belief that its approach was both lawful and constitutional."
Mr Johnson was in New York when the ruling was handed down.
Opposition leaders and parties have called for him to resign in the wake of the court's decision.
Addressing party members at the Labour annual conference on Tuesday, Mr Corbyn insisted Mr Johnson's government "will be held to account for what it has done".
The opposition leader argued: "[Boris Johnson] thought he could do whatever he liked just as he always does. He thinks he’s above us all.
"He is part of an elite that disdains democracy. He is not fit to be prime minister."
Criticism has also been directed at Mr Johnson's senior adviser Dominic Cummings and Geoffrey Cox for their apparent roles in the prorogation decision.
Boris Johnson reaction
Mr Johnson, meanwhile, said he respects the UK Supreme Court's verdict - but 'strongly disagreed' with the justices.
Speaking in New York before his departure, he claimed he is now going to get on with making sure Brexit happens.
He suggested: "We in the UK will not be deterred from getting on and delivering on the will of the people to come out of the EU on October 31st - because that is what we were mandated to do."
Mr Johnson met with Taoiseach Leo Varadkar on Tuesday, only hours after the Supreme Court decision was handed down.
The Taoiseach said the meeting was a useful exchange – but warned that there is still a huge amount of work to do if a deal is to be struck by the end of October.
