Millions of London Underground passengers face disruption throughout the day because of strike action.
The first in a series of 24-hour walkouts began at 1700 BST on Monday with maintenance staff walking out. Drivers, signallers and station staff stopped working four hours later. They are unhappy about plans to cut 800 jobs in ticket offices and say security could be at risk.
