SCOTS are the most adamant in Britain that Boris Johnson should not break the law and ask the EU for a Brexit extension, according to a new poll.

The survey by the pollsters YouGov came before the prime minister reiterated in the House of Commons he would under no circumstances request a delay to the UK's exit from the EU beyond October 31.

The remarks came as legislation forcing the government to request an extension from Brussels until 2020, if a deal is in play by October 19,  received royal assent.

According to the poll carried out between September 6 and 8, when Scottish respondents were asked if Parliament voted to legally require Boris Johnson to go to the EU and ask for a Brexit extension, 63% said the Prime Minister should not break the law and ask for a delay to stop the deadlock. A further 20% said they didn't know.

Only 17% said he should flout the law.

Across the UK half of those polled positively stated that the Prime Minister should not break the law with 28% saying he should.

Scotland's stance against a law breach was stronger than in London (58%), the rest of the south of England (50%), the Midland and Wales (45%) and the north of England (45%).

Among those who voted Conservative at the 2017 general election, half said that Mr Johnson should break the law, compared with 34 per cent who said he should adhere to the extension request.

Of those who voted Leave at the EU referendum in 2016, 52 per cent believed the government should flout the law while 28 per cent disagreed.

Speaking ahead of the suspension of parliament and MPs blocking his bid for a general election a second time, Boris Johnson said he'd rather "die in a ditch" than delay the Halloween Brexit deadline any further.

And he later said that the government would use the time Parliament was suspended to press on with negotiating a deal with the EU, while "preparing to leave without one".

"No matter how many devices this Parliament invents to tie my hands, I will strive to get an agreement in the national interest," he said.

"This government will not delay Brexit any further."

But he was warned that ignoring the new law could prompt a legal challenge while ministers called it "lousy" and said they would "test to the limit" what it required of them.
