Some Tube platforms were packed on Monday morning despite a warning from Sadiq Khan to follow expert advice and avoid the transport network.

Still heavy loading on some Tube lines this morning making social distancing impossible. This is endangering the health of the vital workers who have to use the system. The Government must act now to ensure only ESSENTIAL journeys are made. I'm being sent pictures of crush loaded platforms at some Jubilee line platforms this morning. Drivers and other front line staff are furious.

London's mayor Sadiq Khan has repeatedly said people should only travel if their journey is essential. While some parts of the Tube are virtually deserted others remain busy.

Some people claimed there was little other option for those who needed to travel in for work, since a number of services had been reduced by Transport for London.

Nurse Julia Harris tweeted pictures of queues and a packed carriage at North Greenwich tube station, where trains were running every seven minutes.

Sadiq Khan said no one should ignore the warnings about coronavirus. Speaking last week the mayor said:

I can't say this clearly enough. People should not be travelling by any means unless they absolutely must.
