Members of the Rail, Maritime and Transport (RMT) union are taking part in a six-day walkout between Sunday and Friday which has paralysed London Underground services.

Action will bring services to early finish on Sunday evening and close underground entirely for four days from Monday

Tube staff have launched a full walkout this morning in an RMT-led row with Transport for London (TfL) over pay and conditions, plunging the capital into travel chaos.
