London Mayor Sadiq Khan was challenged on live TV as he claimed there is “no risk” of catching the deadly coronavirus from joining the millions who ride the city’s packed trains and buses.

“It’s very important that we don’t spread panic or alarm based on misinformation,” Khan said on “Good Morning Britain” Tuesday when asked about the assumed “obvious risk factor” of public transport.

“There is no risk in using the Tube or buses or other forms of public transport,” he said, noting there are 5 million journeys each day on the underground system along with 6 million on buses.

Khan also claimed there would be no risk jamming in alongside “between 5,000 and 20,000” people at a packed concert.

Interviewer Piers Morgan instantly challenged him over the claims, which contradicted previous warnings and studies.

“How can you say, as mayor of London, there is no risk to people using public transport?” the former “America’s Got Talent” judge asked, sounding incredulous.

Khan insisted it was based on “advice I receive from Public Health England and the chief medical officer.”

“You’re right, though,” he then conceded of the fact that it is possible to catch it “if we’re in close proximity” to someone who has it.

Morgan later accused the mayor of “spreading mixed messages” after he admitted no longer shaking hands, despite that not being the advice given by the same experts he quoted earlier.
