BREXIT-supporting Conservatives have accused opposition MPs of “disgraceful” and “childish” behaviour as the House of Commons was suspended for five weeks.

Some have also insisted that Boris Johnson can still reach a deal which would prevent him being forced to ask for another delay to Britain’s departure from the European Union.

Legislation passed last week requires Boris Johnson to seek a further Brexit extension if a deal is not reached with the EU by the end of October. The prime minister has said he will not ask for such an extension.

But Mid-Dorset and North Poole MP Michael Tomlinson said it was “ridiculous” to suggest Mr Johnson would not respect the rule of law.

He said: “The letter of the law does not stop no deal.

“He must abide by the letter of the law and by the rule of law – but the letter of the law, however well drafted, does not in fact stop or prevent the prime minister from ensuring we leave on October 31.”

The tactics open to the prime minister might include persuading another EU member to veto a further extension. Mr Tomlinson said it was “possible” that such a veto might happen. ”We know that Europe is getting pretty fed up with us as you can imagine,” he said.

“But the prime thing is if we can get a deal – because if we can, then the act doesn’t have any kind of force,” he added.

There were rowdy scenes in the Commons in the early hours of yesterday morning when it was “prorogued”, or suspended.

Mr Tomlinson said: “It was verging on embarrassing, what happened in the chamber. The chamber shouldn’t be a silent place, it’s not a chapel, not a place of worship. But it should be respectful. That respect comes from the speaker down.

“There were disgraceful scenes that we witnessed last night. I’m hoping when parliament returns that it returns with a sense of respect.”

But although he said both sides needed to behave better, he said the House’s speaker, John Bercow, had “lost his impartiality”.

New Forest East MP Sir Desmond Swayne condemned Monday’s scenes – when opposition MPs remained in the Commons after its suspension – as “an utterly childish demonstration”.

He said: “Imagine singing the Red Flag and Flower of Scotland in the Commons rather that attending the Queen’s speech read by her commissioners in the Lords.”

He said Mr Johnson could “avoid being forced to beg for an extension” by securing a deal.

He added: “Of course, that is a very tall order now that the Commons has sent him naked into the negotiating chamber, but let’s see what he can do.”

North Dorset MP Simon Hoare said in the Commons that he had “not had a single email” from a constituent backing the prorogation of Parliament.

On Twitter, he said he was now “convinced” the prime minister would secure a deal. “I’m detecting both movement and reality dawning. We now need those who say they want a deal to vote for it. It won’t be perfect but what in life ever is?” he added.
