The claim comes amid uncertainty over how Labour leader Jeremy Corbyn would campaign in any second Brexit referendum.
Britain’s main opposition Labour party is pro-EU and wants to stay closely aligned to Brussels, one of its MEPs has told Euronews.
Neena Gill’s claim comes on the day leader Jeremy Corbyn called for a general election to solve the UK’s Brexit deadlock.
British Prime Minister Theresa May is expected to lose a crucial vote on her Brexit deal next Tuesday (January 15).
If that happens it could trigger a vote of no confidence in the government or lead to a second Brexit referendum.
Gill, asked whether Corbyn would campaign to stay in the EU if there was another vote, told Euronews’ Raw Politics programme: “He has said he would campaign to remain. I believe he has been very engaged with the European family and much more engaged than previous leaders.
“Labour essentially is a pro-EU party and want to make sure we stay as closely aligned to the European Union.”
But Euronews’ political editor Darren McCaffrey said Corbyn had been unclear on how he’d campaign in any second referendum.
He said Brexit is as divisive for Labour as for the ruling Conservatives. That is because Corbyn’s party holds the 10 most pro-remain constituencies in the UK but also the areas that most-heavily back quitting the EU.
“At the last election, Labour stood on a manifesto in which they said they would leave the European Union, they would fulfil the result of the referendum and that they would leave the single market and the customs union,” he added. “Jeremy Corbyn is having to play a very, very difficult political game here.”
