UK departure from the EU should be complete
How long will it take for Britain to leave the EU?
Article 50 is triggered and the UK have two years to negotiate its withdrawal. But no one really knows how the Brexit process will work – Article 50 was only created in late 2009 and it has never been used. Former Foreign Secretary Philip Hammond, now Chancellor, wanted Britain to remain in the EU, and he has suggested it could take up to six years for the UK to complete exit negotiations. The terms of Britain’s exit will have to be agreed by 27 national parliaments, a process which could take some years, he has argued.
