EU chief Brexit negotiator Michel Barnier said today that the March 29 exit date could be extended. But that should be for a reason. He said “If it is asked, European leaders will say ‘What for?’ and the duration of this potential extension will be linked to ‘What for?'”.
He added that a “technical” extension could last until European parliament election in May. And, longer than that, there will be issues regarding Britons voting in the European election.
