Mr Corbyn, who has been having talks with Theresa May to try and forge a deal that they could put to parliament, has made clear he was not in favour of a second referendum in all circumstances. However, Miss Thornberry wrote to all Labour MPs saying: “Any deal agreed by Parliament must be subject to a confirmatory public votes, and yes, the other option on the ballot must be Remain.” The Shadow Foreign Secretary has demanded a ballot on the deal that emerges.

Mr Corbyn’s spokesman has insisted he only favours a fresh public vote to “prevent a damaging Tory Brexit or a no-deal outcome”.
A protest at the end of March demanding a second Brexit referendum was the largest in the UK since 2003 and attracted a reported more one million people.
Trade union Unison has also put pressure on Mr Corbyn to have a second referendum.
Unison General Secretary Dave Prentis said: “Whatever deal emerges in the coming days should be put to the country. We cannot allow the UK’s future to be dashed on the rocks of a No Deal Brexit.”
In a statement last month the leaders of the SNP, Lib Dems, , Plaid Cymru and the Green Party: “The UK faces an unprecedented crisis with Brexit, and Westminster remains deeply divided. The best and most democratic way forward is to put the decision back to the people in a new vote – with the option to Remain on the ballot paper.
“We are in agreement that there is no such thing as a good Brexit. We are clear that retaining our EU membership is the only way to protect jobs, living standards, our public services, the environment and the economy. And it is important that we will retain all of our rights as EU citizens”
The Scottish Brexit Secretary Mike Russell has said the ‘best outcome’ for the current deadlock in Brexit talks would be a long delay to the UK’s exit and a second referendum.
Mrs May is expected to meet EU leaders at the emergency summit called by European Council president Donald Tusk on April 10 and, if Brussels agrees to further delay Brexit, MPs will have to support the Article 50 extension with another vote on the following day.
