Jeremy Corbyn is facing a mounting backlash from within his own party for supporting striking rail unions as one of his closest allies took to the picket lines.

The London Underground suffered almost complete shutdown of the network in the city centre after two unions staged a walkout over ticket office closures, hitting millions of commuters.

The industrial action led to chaos in London, with one of the capital's biggest stations evacuated over safety concerns and hour-long queues to board buses.

Rail services across the South East will on Tuesday come to a halt as Southern Rail train drivers go on strike, leaving more than 300,000 commuters struggling to get to work.
