London travellers face transport chaos today due to a strike by Underground workers over proposed job cuts and ticket office closures.

The first of two 48-hour walkouts started last night at 9pm resulting in only a limited Tube service running until Friday morning.

A second 48-hour Underground walkout is due to begin at 9pm on February 11.

About 100 extra buses are being laid on in the capital but millions of passengers face major travel disruption.

The industrial action comes as various rail networks impose speed restrictions across sections of lines across the southeast and southwest of England due to strong winds and rain.

Parts of Southeastern and South West Trains’ networks are among those affected, with all lines between Exeter St Davids and Penzance closed.

Network Rail imposed a 40mph speed restriction across parts of the Southeastern network because of a risk of further flooding, landslips and falling trees.

South West Trains said a speed limit of 50mph would apply on some routes between 10am and 7pm today.
