London Underground workers have voted to strike for five days over the closure of ticket offices.
Members of the Rail, Maritime and Transport (RMT) union will walk out for 48 hours from 9pm on Monday April 28 and at the same time on Monday May 5 for 72 hours.
The strike is in response to plans from Transport for London to close 260 ticket offices and cut a possible 960 jobs.
In February, Tube workers went on strike for two days against closures.
A second two day strike in the same month was called off following the announcement of a possible deal between unions and TFL.
