"The motion before the Labour conference doesn't rule out a second referendum", Brendan Chilton, general secretary of the Labour Leave campaign, told Reuters.
The shadow chancellor told BBC Radio 5 Live: "We argued for Remain in the past, but we lost that vote so we have to respect that". "And if there is a general election and we are in office we would go straight to the negotiating table".
Joan Ryan, Gavin Shuker and Chris Leslie have all blamed the hard-left who have flooded into the party after they were hit by the votes.
