LONDON - Britain should begin informal negotiations on a full settlement governing its post-Brexit relationship with the European Union before invoking Article 50 of the Lisbon Treaty, the chief executive of the Vote Leave campaign said on Saturday.
"We don't think there is a need to swiftly invoke Article 50," Matthew Elliott told Reuters in an interview.
"It's best for the dust to settle over the summer and during that time for there to be informal negotiations with other states," he said.
Britain was under pressure on Saturday to set out a quick timetable for a divorce from the EU after the country's historic vote to leave the bloc sent shockwaves around the world, though signals from the rest of Europe were contradictory.
European Commission President Jean-Claude Juncker said he wanted to begin negotiating Britain's departure immediately while German Chancellor Angela Merkel said that there is no desperate rush for Britain to trigger the formal exit negotiation.
