UK opposition leader will back second Brexit vote if party wants it

British opposition leader Jeremy Corbyn said on Sunday he would back a second Brexit referendum if his Labour Party votes to pursue the move, heaping pressure on Prime Minister Theresa May, whose plans for a divorce deal with the EU have hit an impasse.Corbyn, a veteran eurosceptic, has resisted growing demands to back a new "People's Vote" on the decision to quit the European Union, keen to keep those party members on board who voted in favour of Brexit at a 2016 referendum.
