Liberal Democrats call for second EU referendum in December 2018

Britons should be given the chance to vote on Brexit again in 12 months time, according to the Liberal Democrats.
The party has set out a timetable for its demand for a second EU referendum on the final Brexit deal before the UK leaves the bloc in March 2019.
Under their proposed schedule, Parliament should legislate for another nationwide vote on EU membership once the EU Withdrawal Bill completes its passage through Parliament - estimated for April 2018.
Following a 12-week campaign beginning in September next year, Britons would then go to the polls in December 2018, the party said.
If Remain wins, the UK's invocation of Article 50 of the Lisbon Treaty - the legal mechanism for withdrawal - would then be reversed under the Liberal Democrats' plans.
The timetable matches the EU's plans for ratifying the final Brexit agreement, with the European Parliament and European Council due to give their verdicts on the negotiated deal between September and December next year.
The Liberal Democrats set out their proposal ahead of the EU Withdrawal Bill completing its latest stage in the House of Commons on Wednesday, when MPs will debate the prospect of a second EU referendum.
The party, which opposes the UK's exit from the EU, has introduced an amendment to the key Brexit legislation calling for the Government to only be granted powers to repeal EU law once the public has approved a Brexit deal.
It is urging Labour MPs to back the change to the bill, although it is unlikely to pass.
Leader Sir Vince Cable said: "This potential timeline to a public vote shows Brexit is not a done deal.
"It can be stopped, but not without the approval of the British public. It's time the Conservatives - and the Labour leadership - listened."
MPs will also use Wednesday's debate on the EU Withdrawal Bill to consider another amendment from Labour MP Chris Leslie, which calls on the Government to keep Britain in the EU's Customs Union.
The former shadow chancellor's amendment could attract the support of Labour rebels.
Meanwhile, the Government appears to have avoided another revolt on Tory benches by conceding to some flexibility on its plan to write the Brexit date of 29 March, 2019, into law.
The debate comes after Labour's frontbench sparked confusion over their position on a second EU referendum.
Deputy leader Tom Watson on Sunday, but three of his shadow cabinet colleagues insisted it was not Labour policy.
At the weekend, a BMG poll revealed a ten-point lead for Remain (51%) over Leave (41%), while a Survation poll showed 50% support for a referendum on the final Brexit deal with 34% opposed and 16% saying they did not know.
