Tube carriages remained packed this morning, despite a number of key workers pleading with Sadiq Khan to stagger service levels.

Pictures have flooded the internet of tightly packed tubes, with commuters having to stand close together, with no space to social distance.

Health Secretary Matt Hancock has claimed there is 'no good reason' why timetables have been cut to the extent that they have.

But Sadiq Khan's spokesman insisted ministers were told 'countless times' that Tube frequencies reflect high levels of staff sickness and self-isolation.

Several key workers have taken to Twitter to address their outrage on service times.

Danny, a senior nurse said: "Another busy tube.

"Can we not stagger people's start times so we aren't all squashed on the same tube.

" This is unsafe and not fair."

Barry Trimble, who said his work involves ensuring cancer patients receive chemotherapy, posted: "The Tube is packed, with social distancing impossible.

"We need more people to stay at home and more trains running in morning and evening peak."

Health Secretary Matt Hancock said: "Transport for London should have the Tube running in full so that people travelling on the Tube are spaced out and can be further apart.

"There is no good reason in the information that I have seen that the current levels of Tube provision should be as low as they are.

“We should have more Tube trains running."

In response, Sadiq Khan's spokesman said nearly a third of staff are absent, which means there aren't enough drivers and control staff to run a full service.

Transport for London has pledged to continue to run as much of a Tube service as they possibly can.
