Business owners in London have been warned that members of a union have voted to go on strike over proposed job cuts on the London Underground.

The Transport Salaried Staffs Association (TSSA) said its workers voted 3-1 in favour of industrial action.

The strike is likely to go ahead next month, with September the 6th - when MPs return from Westminster - the most likely date. TSSA's leader Gerry Doherty and RMT general secretary Bob Crow are expected to meet and announce the strike dates on Tuesday.

Last week the Rail Maritime and Transport (RMT) union voted to go on strike at plans to cut 800 jobs in ticket offices across the network.
