The French President also suggested the UK might be refused any further delays to leaving. Speaking alongside Irish Taoiseach Leo Varadkar at the Elysee Palace he said credible justifications for an Article 50 extension could include an election, second referendum or alternative proposals for the future relationship, such as a customs union. But he warned: “A long extension involving the participation of the UK in European elections and European institutions is far from evident and certainly not to be taken for granted.
“Our priority shall be the good functioning of the EU and the single market. The EU cannot be the hostage to the solution to a political crisis in the UK.”
He added: “We cannot spend the coming months sorting out yet again the terms of our divorce and dealing with the past.”
Mr Macron’s remarks were the latest in a long line of antagonistic interventions.
Last month he branded Brexit an “irresponsible lie”, calling it the worst crisis since the Second World War. He said Brexit was peddled by “anger mongers and fake news”.
Mr Varadkar took a more conciliatory tone: “We’ll need to consider how we respond to any request for a long extension, that will involve UK participating in EU elections and we want to avoid a rolling extension, so any extension must have a clear purpose and plan.”
