Ex-PM John Major warns that Boris Johnson could use ‘political chicanery’ to SUSPEND Remainer rebels’ law against No Deal and force Brexit on October 31

In a speech to the Centre for European Reform, Sir John suggested the government could try to bypass the Benn Act by issuing an executive Order in Council.

That does not require the permission of the Queen, and could potentially suspend the law until after October 31.

'I should warn the Prime Minister that - if this route is taken - it will be in flagrant defiance of Parliament and utterly disrespectful to the Supreme Court,' Sir John said.

'It would be a piece of political chicanery that no-one should ever forgive or forget.' 

In a stinging attack, Sir John accused Mr Johnson of 'wilfully' destroying any chance of a cross-agreement on Brexit after his attack on the opposition in the Commons on Wednesday.

The Tory former leader said Mr Johnson was whipping up 'fear and anger' for electoral purposes - a tactic he described as 'profoundly un-Conservative'.

Sir John said that the Tories were acting as a 'Brexit Party tribute band' and that no previous government would have behaved in such a 'reckless and divisive' manner.

He also claimed that Mr Johnson had only given 'lip service' to the Supreme Court ruling that the prorogation of Parliament had been unlawful and warned he could try to circumvent the law designed to prevent a no-deal break.

Sir John said he increasingly feared the country was heading for a no-deal Brexit, and that any new deal with Brussels was likely to be 'flimsy and partial'. 

At the same time, he warned that a general election - which Mr Johnson is pressing for - would not achieve anything unless the Brexit issue had been resolved first.

'To reinforce their electoral appeal, the Government seems intent on whipping up dissent by using highly emotional and evocative language that can only provoke fear and anger, and fuel grievances against Parliament and the law,' he said.

'It means this Government wishes to win re-election, by inciting opposition to the most important bulwarks of our state and its freedom.

'Their approach is profoundly un-Conservative and - whatever its short-term effect - will do permanent damage to the reputation of the Conservative Party.

'I cannot believe any previous government - in our long history - would have even considered such reckless and divisive behaviour.'

Sir John said that Mr Johnson's negotiating strategy appeared to be driven by a desire to win the support of the 'anti-European hard right' of the Tory Party.

'It was always likely to be a fruitless task,' he said.

'They were appeased too much; for too long; and by too many. But they held to their convictions and spread them - often without reason and beyond scruple.

'Their opposition has made a deal almost impossible to obtain.'

He warned that such tactics risked alienating the party's 'traditional, moderate, middle-of-the-road' supporters.

Sir John said: 'Most Conservatives are not a Brexit Party tribute band, nor have we abandoned our core values to find compromise, seek allies, and strive for unity, rather than division and disarray.

'We abhor the language of division and hate - and words such as 'saboteur', 'traitor', 'enemy', 'surrender', 'betrayal' have no place in our party, our politics, nor in our society.

'It is emphatically not who we are as a people. And must never be seen as so.'
