Things could be about to get worse for commuters as tube drivers have voted strike to after the sacking of a colleague.

Members of the Rail, Maritime and Transport Union backed industrial action by 299 votes to 221.

London Underground urged union members to vote against strike, insisting they had dismissed the Northern Line driver for failing two random breath alcohol tests, adding that it operates a zero tolerance policy for drugs and alcohol.

Union general secretary, Mick Cash, said: "Our members have voted for industrial action and the union will consult extensively with our representatives before deciding on our next moves in this dispute.

"The union remains available for talks, at Acas if necessary, and as we have already states we are ready to abide by any decision made at an Employment Tribunal and cannot understand London Underground's reluctance to agree to that course of action."
