British opposition Labour leader Jeremy Corbyn said on Wednesday it was "right to demand" a second referendum on any Brexit deal, his strongest backing yet for a vote he said must offer "real choices" for both those who want to leave and stay in the EU.
Corbyn, an instinctive critic of the European Union, has been under growing pressure to back unequivocally a second referendum to satisfy many members and lawmakers in his party who say it is the only way to break the Brexit deadlock.
He has previously showed his preference for a new national election, almost three years since Britain voted to leave the EU, which left both his party and the governing Conservatives deeply split over how, when and whether Brexit should happen.
