Two MPs have cancelled events after attending a UK bus summit with a person diagnosed with coronavirus.

Labour's Alex Sobel and Lilian Greenwood both said they would be cancelling all their engagements until next week.

Mr Sobel, MP for Leeds North West, wrote on Twitter that he has called NHS 111 to be assessed.

It was first reported that Mr Sobel would be self-isolating for 14 days, but a spokesman for Mr Sobel has since confirmed he is no longer isolating himself after being established as low-risk by NHS 111.

"He will stay away from public engagements as a precautionary measure," he added.

Both Mr Sobel and Ms Greenwood were at the UK Bus Summit in the QEII centre in Westminster on February 6 along with 250 delegates from the nationwide bus and transport industry.

Transport Times, the conference organiser, emailed attendees on Thursday afternoon, informing them that a person confirmed to be suffering from coronavirus illness - known as Covid-19 - had been at the event.

Mr Sobel tweeted: "I attended the UK bus summit on the 6th Feb, where there was an attendee who has tested positive for coronavirus.

"Whilst I have been informed that I am at very low risk, I have called 111 to be formally assessed."

Speaking to Sky News, Mr Sobel said he had isolated himself in the back room of his constituency office before moving to his home office, which he intended not to leave until next Wednesday.

He said: "I've got a pile of things to do, like MPs do. Things to read, things to write, Netflix to watch."

He also warned the virus had potential to become a "pandemic" and must be the government's top priority.

Ms Greenwood, who spoke at the summit, tweeted that she had received Public Health England's letter, advising her to stay indoors and avoid contact with other people if she were to develop symptoms of cough or flu.

She wrote: "I'm feeling completely well but to be extra-cautious I'm cancelling my public engagements until 20th February. Sorry for any inconvenience."​

It is understood that the person who attended the event is not linked to the ninth patient with coronavirus in the UK.

Dr Yimmy Chow, consultant in health protection at Public Health England (PHE), said: "One of our main priorities has been to identify any people who we think have been in close contact with confirmed cases of Covid-19 to provide public health advice, as they may be at slightly increased risk of catching the virus.

"While the degree of contact conference delegates may have had with the case is unlikely to have been significant, we have taken a precautionary approach and informed them of the situation."
