Thousands of London Underground workers will start a 24-hour strike on Sunday evening, threatening travel disruption for commuters and other passengers.
Members of the Rail, Maritime and Transport Union and the Transport Salaried Staffs' Association will walk out at 6.30pm in protest at 800 ticket office job cuts.
It will be the fourth stoppage in recent months in the bitter row which has been deadlocked for months.
Transport for London said it will run as many Tube services as possible, although it warned there will be disruption throughout the whole of Monday, with services returning to normal on Tuesday.
