London Underground Passengers Have Been Crowding on to Tube Trains

Images from Monday's rush hour show busy carriages, which unions say left staff feeling "furious" as it rendered social distancing "impossible".

London Mayor Sadiq Khan has urged workers to stay at home and said public transport should only be used by key workers, otherwise "people will die".

Some passengers have said a reduced service means trains are busier.

Aslef union's district organiser Finn Brennan tweeted: "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."

He called on the government to act, adding: "I'm being sent pictures of crush loaded platforms at some Jubilee line platforms this morning.

"Drivers and other frontline staff are furious."
