Britain's opposition Labour party leader Jeremy Corbyn on Tuesday declined to say if his party would stop the Brexit process to form a coalition if no party won a majority in December's election. Asked if Labour would revoke Article 50 in order to secure the support of the Liberal Democrats in a hung parliament, Corbyn said: 'All I can say is: we are campaigning to win this election with a majority Labour government. We are not campaigning to form a coalition with anybody.'
