The London mayor has made an urgent appeal for Londoners to stop using public transport, unless they really need to.

Sadiq Khan made the plea as the UK enters its third week of lockdown to try and curb the spread of coronavirus.

He said it's important to keep transport system clear for key workers, which includes NHS staff and care workers.

In the tweet, Sadiq Khan said: "Reminder: Londoners must work from home wherever possible to protect our key workers who need to travel.

"If you have to go to work, please don’t travel at rush hour.

"We cannot run more services due to numbers of @Tfl staff off sick or self isolating"

According to Transport for London if people's journeys are absolutely essential, the busiest times are 5.45am to 7.30am and 4pm-5.30pm.

In a recent interview with Sadiq Khan on Good Morning Britain, Piers Morgan described the overcrowding on the London Underground as a "death trap".

Yesterday, the mayor confirmed ten transport workers had died after contracting coronavirus.
