Responding to the disagreement between John McDonnell and Len McCluskey, the Unite leader, Liberal Democrat Brexit Spokesperson Tom Brake said:
"Whilst we appreciate that McDonnell has dismissed Len McCluskey’s nonsense and joined the Liberal Democrats in saying he would back staying in the EU over the Prime Minister’s deal in a people’s vote, this is not the time for just warm words.
"The shadow chancellor and the rest of the Labour leadership must get off the fence and join their members of the Labour Party in supporting a people’s vote. The public will never forgive Labour if the frontbench lose their bottle on Brexit.
"The Liberal Democrats can guarantee we will fight for the people to have a final say on Brexit, including the option to remain, at every opportunity. Labour must give that unequivocal guarantee too.”
