LABOUR’S Kate Osborne has become the second MP to test positive for coronavirus, it emerged today, as House of Commons authorities announced restrictions on visits to Parliament.

“I will continue to self-isolate until I have fought off the illness,” Ms Osborne wrote in a social-media post after receiving her results on Sunday night.

“But in the mean time, I would encourage everyone to band together and support the most vulnerable in our communities.”

The Jarrow MP urged anyone experiencing symptoms to self-isolate and call 111 for advice.

Shadow immigration minister Bell Ribeiro-Addy posted that she had gone into isolation after showing symptoms of Covid-19.

She said: “Sorry to report that I’ve been self-isolating after experiencing #coronavirus symptoms over the weekend.”

The Streatham MP added that her constituency office has been closed as a “precautionary measure” but that her email was still being monitored.

Health Minister Nadine Dorries became the first MP to test positive for coronavirus last week, prompting several MPs to begin self-isolation after coming into contact with her.

Prime Minister Boris Johnson refused to undergo testing despite having been in close proximity to Ms Dorries a few days before her diagnosis.

The restrictions on visiting the Palace of Westminster include the cancellation of all commercial tours and a ban on mass lobby groups. But the Commons authorities stressed that MPs’ work should continue as normally as possible.

Last week, Ms Ribeiro-Addy raised concerns about the risks of Parliament continuing to sit.

Addressing Health Minister Matt Hancock, she said: “As we continue to meet hundreds of people weekly, I am concerned that we are potentially spreading the virus.

“My biomedical training tells me that a number of members in this house probably already have the virus.

"I am genuinely concerned about older members, older constituents and those with underlying health conditions.”

Many politicians around the world have fallen victim to the virus, probably because they come into contact with large numbers of people daily.

They include Iranian Deputy Health Minister Iraj Harirchi, who was leading his country’s fight against the disease, French Culture Minister Franck Riester and both leaders of Spain’s far-right Vox party, Santiago Avascal and Javier Ortega Smith.
