It would be the “end of democracy” in the UK if Boris Johnson closed down parliament in order to force a no-deal Brexit, Dominic Grieve has warned.
The senior Tory backbencher is behind moves today to prevent the next prime minister taking the UK out of the EU on October 31 without an agreement.
“The idea it is constitutionally proper to prorogue parliament as a device for bringing about a no-deal Brexit is outrageous. I have never comer across a more extraordinary suggestion,” Grieve told BBC Radio 4′s Today programme.
“It’s the end of parliamentary democracy isn’t it - if you decide parliament is an inconvenience when in fact it’s a place where democratic legitimacy lies in our constitution.”
Grieve, a former attorney general, has tabled an amendment to the Northern Ireland Bill - intended to keep government in the province running in the absence of the devolved institutions - requiring parliament to come back to the issue in October.
The move is designed to try to ensure the next prime minister cannot push through a no deal at the end of October, the current EU deadline for agreeing on a deal, simply by suspending - or “proroguing” - parliament.
Commons Speaker John Bercow is expected to announce on Tuesday whether he has selected the amendment for debate, giving MPs the chance to vote on it.
Johnson, who has said he will take Britain out of the EU by the end of October “do or die”, warned such tactics risked playing into the hands of Jeremy Corbyn and Labour.
Johnson was also told today by Conservative Party ex-leader William Hague to rule out suspending parliament.
Lord Hague said the frontrunner in the battle for Downing Street should use a head-to-head TV debate with rival Jeremy Hunt on Tuesday to make clear he would not use a parliamentary “manoeuvre” to impose a no-deal exit.
The former party leader, who backs Hunt in the leadership race, told the BBC: “It is very important that parliament is able to give its opinion.
“It ought to be unthinkable that we could leave the European Union by a manoeuvre, by a procedural ruse of some kind.”
Asked if Johnson should rule out proroguing Parliament to get a no-deal Brexit, Hague said: “He should rule it out. Yes.”
Hague added: “For a Conservative government to go ahead with a no-deal Brexit in defiance of the pleas of business and farming organisations, and increasing the risks to the union of the United Kingdom, and defying any attempt to have a vote in parliament would be an extraordinary combination of things to do.”
The two contenders to succeed Theresa May will appear on a live ITV debate at 8pm on Tuesday which could help to decide the outcome of the contest.
Johnson will hope to use the occasion to seal his position as the clear frontrunner, with polls giving him an overwhelming lead among party members.
For Hunt, the foreign secretary, it potentially offers a final chance to turn around a contest in which he has been the underdog throughout.
There has been frustration in the Hunt camp at the reluctance of his rival to engage in direct debate.
Although both men have taken part in numerous hustings - where they take questions separately from party members - Johnson has agreed to take part in only one previous TV debate, when there were still five contenders left in the race.
Ballot papers started going out last week to the party’s estimated 180,000 members, and many will already have voted, meaning that the potential for the debate to alter the course of the contest may be limited.
At a hustings organised by The Daily Telegraph on Monday, Johnson issued a fresh warning to Tory MPs seeking to block a no-deal Brexit.
“If we don’t get Brexit over the line then we face a haemorrhage of support,” he said, according to The Telegraph.
“The risk they run is we will hand, by sheer incompetence, this government to a hard line Marxist.
“I make that point to Dominic Grieve and others who didn’t want to leave the EU. We’ve been very, very negative. We need to be much more robust and confident.”
Hunt said that he believed he would be able to get a new deal with Brussels - but if that proved impossible, he would “batten down the hatches” and prepare for no deal on October 31.
“I strongly believe if we approach this in the right way, there is a deal to be done,” he said, according to The Telegraph.
He went on: “In September I take it to the EU. At the end of September, I make a judgment: ‘Is there a deal to be done here?’
“If there isn’t one, we will batten down the hatches and be ready for October 31.”
