But in an extraordinary development that followed a bruising defeat in Parliament, he simultaneously disowned the request, declaring that the three-month delay would be “corrosive.”
Downing Street demonstrated Johnson’s disdain for the process by sending an unsigned photocopy of the legally mandated letter by email to the EU Council President, Donald Tusk. It was accompanied by a covering letter from a senior civil servant explaining that the letter was being sent in order to comply with a law passed by Parliament last month which is designed to prevent a no-deal Brexit.
A third letter was sent to EU leaders, in which Johnson explained why the delay was a bad idea. It would be “deeply corrosive,” he wrote in the letter, according to a UK government source. Tusk said he had received the correspondence and would consult with other EU leaders on next steps.
“I will not negotiate a delay with the EU, and neither does the law compel me to do so,” Johnson had told lawmakers earlier. “Further delay will be bad for this country.”
The Labour leader, Jeremy Corbyn, blasted Johnson from across the floor of the House of Commons. “The Prime Minister must now comply with the law,” he said. “He can no longer use the threat of a no-deal crash-out to blackmail MPs to support his sellout deal.”
Moment of victory denied
Government aides were furious at the result of the vote in Parliament, as it denied Johnson the chance to declare a Brexit victory on Saturday. After two days of arm-twisting since Johnson returned with a new deal from Brussels on Thursday, Downing Street believed it had secured the numbers required to pass it, albeit by a razor-thin margin.
Johnson’s nemesis was former Conservative government minister Oliver Letwin, expelled from the party when he voted for the law that prevents a no-deal Brexit. Proposing the measure that delayed Parliament’s approval, Letwin said it was an “insurance policy” to ensure the UK would not “crash out” of the European Union without a deal on October 31.
Under legislation known as the Benn Act, the UK government was required to request an extension to the Brexit process until January 31, if a deal was was not ratified by the end of Saturday.
Those provisions would have fallen away if Johnson had succeeded in getting his deal through the House of Commons. But Letwin and his allies were concerned that a no-deal Brexit could still happen at the end of October if, by then, lawmakers had failed to pass the complex set of legislation required to enact the departure deal.
In a twist of political fate, the outcome was decided by the 10 MPs of the Democratic Unionist Party, the Northern Ireland group that nominally props up Johnson’s minority government in the House of Commons.
The DUP was deeply unhappy with terms of Johnson’s deal, under which Northern Ireland effectively remains in the EU customs union, separating the province economically from the rest of the UK. Its MPs were particularly furious that Johnson had cast them aside, traveling to Brussels on Thursday to sign his Brexit deal with EU leaders without securing their support.
“We are cut off from the country to which we belong,” said Sammy Wilson, the DUP’s Brexit spokesman, in an impassioned speech in the House of Commons.
What happens next?
Johnson’s contradictory correspondence to the EU is bound to land him in front of a judge. A related case was already due to be heard at Scotland’s highest court, the Court of Session in Edinburgh, on Monday, and this will likely be the venue for the first legal challenge.
Joanna Cherry, the Scottish National Party lawmaker who has led many of the legal challenges over Brexit, confirmed the hearing would go ahead.
Opposition lawmakers were furious at the developments. John McDonnell, Labour’s finance spokesman, said on Twitter: “Johnson is a Prime Minister who is now treating Parliament and the Courts with contempt. His juvenile refusal to even sign the letter confirms what we always suspected that Johnson with his arrogant sense of entitlement considers he is above the law and above accountability.”
Meanwhile Jacob Rees-Mogg, the leader of the House of Commons, said the government would bring forward another vote on Johnson’s Brexit deal on Monday.
Ordinarily, the same provision can’t be voted on twice in a parliamentary session. That convention scuppered ex-Prime Minister May’s plans to hold repeated votes on her withdrawal deal. But it was not clear whether Saturday’s proceedings in Parliament counted as a vote on Johnson’s deal, because it was amended by the Letwin measure. Speaker of the House John Bercow said he would rule on the matter Monday
