Britain will need years to negotiate a future trade deal with the European Union after it quits the bloc and will be landed with a “very hefty bill” from Brussels on leaving, EU chief executive Jean-Claude Juncker said on Tuesday.

Noting that the Brexit talks expected to be launched next month would last two years before Britain withdraws from the bloc, Juncker said in a speech to the Belgian parliament: “To agree on the future architecture of relations between the United Kingdom and the European Union, we will need years.”
