Millions of commuters face serious travel disruption in London this morning, after striking Tube workers brought the Underground to a standstill.

The RMT union has called its members out in a dispute over a new pay deal, and London Underground is running just a few of the normal 500 rush-hour services.

The strike began at 6.30pm yesterday and will finish at 6.30pm today, although services are not expected to return to normal until tomorrow morning.
