The date was to be offered at the leaders’ summit last week if Theresa May had followed through on her promise to request a short extension in the event of passing her Brexit deal, and a longer one should it be rejected again by the House of Commons.
Such was the disapproval of her cabinet, the prime minister only sought a short delay until 30 June in her formal letter. She was subsequently given an unconditional extension until 12 April, or a longer one to 22 May in the unlikely event of the withdrawal agreement being ratified this week.
Without having received a request from Downing Street for a prolonged extension, the EU’s leaders instead left open the offer of a lengthy delay should there be a new political process or event before 12 April, such as a general election or second referendum, but they did not stipulate its potential length.
A one-year extension, ending on 31 March 2020, was, however, written into internal EU papers before the summit as an offer that could be made to May should she formally seek a longer extension, sources said. It will likely remain an option if May comes back to Brussels having failed to ratify her deal.
Such a UK departure date would ensure the British government would not have any opportunity to meddle in the EU’s long-term plans, including its budget, sources suggested.
“That would safeguard our work during this year and basically allow us to turn to it again early next year,” the official said. “Giving more than that time runs the risk of mischief by the UK. We have seen the talk of Brexiters of trying to stay in and cause trouble. So such a time limit is not a bad idea.”
Sources emphasised that no decision had been made and it would be the subject of intense debate among the leaders at a summit, likely to be held on 10 April in Brussels, should May come back again for extra time.
“It will be at least until the end of the year, certainly,” the official said of the extension. “We don’t want to come back in October on this. We want to do other things and not have this dominate.”
The source added: “It may be up to two years, but that is the span of the imagination of those who are talking about a long extension. It is not up to this October because we can’t do this all the time. We do need time to do other things. And that is one of the attractions of a long extension. We can put it to one side and do other things.”
The new timelime emerged as Guy Verhofstadt hailed Saturday’s Put it to the People march in London and a petition with more than 5m signatures calling for article 50 to be revoked.
The European parliament’s lead Brexit negotiator said he was very pleased MPs had voted to take control of Brexit from the government.
“We see at the moment a real Brexit revolt,” he said. “Until now, all the Commons votes have been against something. This is the first time that there is a vote for something – cross-party cooperation. We have long called for that.
“It is possible now to work for cross-party proposals and an alliance that could change the political declaration fundamentally. It is very important that this cross-party cooperation will start and I hope it leads to proposals that can be backed by a majority.”
Philippe Lamberts, an MEP on the parliament’s Brexit steering group and a co-leader of Green MEPs, offered a damning analysis of May’s leadership.
“Theresa May might be tempted to play [a] scorched-earth policy and say: ‘Whatever parliament wants, I won’t do it,’” he said. Lamberts added that May had even managed to upset Luxembourg’s prime minister, Xavier Bettel, whom he described as “Mr Nice Guy”, suggesting the British prime minister “must be totally devoid of the basic human skills you need to be a political leader”.
