Boris Johnson was last night urged to bury his doubts and press ahead with Heathrow's third runaway amid fears he could use a potential legal setback this week to ditch the plan.

London Mayor Sadiq Khan swiped that potential rival Mike Bloomberg 'gets under the skin' of Mr Trump because he was wealthier and more successful.

Boris Johnson joked that he was still carrying out the traditional greeting 'continuously', citing scientific advice that it is fine as long as you keep washing your hands.

The Rail, Maritime and Transport union said it is balloting 10,000 Tube staff for strikes and other forms of action in London. The union said more than a year of negotiations have failed.

Mayor of London Sadiq Khan says that steps could be brought in within a matter of days as the capital is weeks ahead of the rest of the country in terms of the curve of the Covid-19 outbreak.

Commuters crowded close together on a packed London Underground train this afternoon, despite official advice that people are at risk if they stand within two metres of an infected person.

The Mayor of London has hit out at people who continue to go to pubs and use public transport, warning he will 'infringe' their human rights if necessary.

Transport for London will temporarily suspend all road user charging schemes from Monday until further notice, to help critical workers move around the capital during the coronavirus crisis.

Mayor Sadiq Khan said public transport should only be used for critical workers in a bid to stop the spread of coronavirus. But the reduced transport services have only exacerbated the situation.

The London Mayor has said Britons in the capital need to stay indoors to 'protect the ones they love' amid the coronavirus outbreak. Commuters were seen lining up to board the Tube today.

Health Secretary Matt Hancock delivered a stinging rebuke to Sadiq Khan saying the Tube should be running 'in full' so essential workers do not have to be close together.

Carriages are packed with key workers again because of an insufficient number of trains to carry people with no choice but to go to work in central London to guide Britain through the crisis.

The Mayor of London claims 'too many people are not staying at home' and again insisted they could not run any more services as he admitted only around half of all trains are now running.

ANDREW PIERCE: Social media posts can be ever so revealing. Who is the unlikeliest fan of ­Labour's new leader Sir Keir Starmer?

A total of 10 public transport workers in London have now died of coronavirus, Sadiq Khan has confirmed. He revealed more than 25,000 people are still working for Transport for London.

Angry London commuters today called the situation 'ridiculous' and a 'mess' as they shared pictures of crowded platforms and trains with travellers standing just inches away from each other.

The approach is meant to reduce contact between the driver and their passengers, but critics - including the families of Transport for London workers - insisted it did not go far enough.

EXCLUSIVE: Hardworking drivers with families to support have been receiving as little as £153.32 per week, forcing them to choose between self-isolation and putting food on the table.

A south London bus driver is urging Transport for London and Sadiq Khan to put drivers' lives 'before profit' as the number of TfL workers dying with Covid-19 rise to 18 today. Lorraine, 63, said she is 'frightened'.

NHS nurse Michael Underwood slammed Transport for London and Mayor Sadiq Khan and compared his journey to 'jumping off a cliff.

Posting a number of pictures showing carriages in London packed with passengers, workers this morning have starkly warned that 'TfL is helping to spread the virus'.

Photos this morning showed commuters at London stations such as Canning Town and Leytonstone boarding busy trains.

JOHN ILLMAN - I welcome the news that London mayor Sadiq Khan is campaigning to make mask wearing compulsory for people travelling in the capital during the crisis. Others must soon follow.

London mayor Sadiq Khan has urged the Government to change its advice on masks to combat the spread of the virus. Debate is now being sparked, as the cabinet set about trying to get people back in work.

The Rail, Maritime and Transport union said it would not accept 'unsafe directives being handed down on high' amid claims that rail services will be increased by May 11 or May 18.
