Health Minister Nadine Dorries is first MP to test positive for coronavirus

The Conservative MP said she has been self-isolating at home after testing positive, and her parliamentary office has closed following advice from Public Health England.

It came after the number of cases in the UK rose to 382, and a sixth death was confirmed.

In a statement on Tuesday night, Ms Dorries said: "As soon as I was informed I took all the advised precautions and have been self-isolating at home.

"Public Health England has started detailed contact tracing and the department and my parliamentary office are closely following their advice.

"I would like to thank PHE and the wonderful NHS staff who have provided me with advice and support."

The Department of Health and Social Care (DHSC) said she first exhibited symptoms at some time on Thursday - the same day she attended a Downing Street event hosted by Boris Johnson to mark International Women's Day.

Number 10 did not comment on whether the Prime Minister had undergone testing for the coronavirus, or whether he will now be tested.

A DHSC spokeswoman said Ms Dorries, the 62-year-old MP for Mid Bedfordshire who began her career as a nurse, has been self-isolating at home since Friday.

Mr Hancock insisted on Monday he will "do all that I can" to keep Parliament open during the coronavirus outbreak.
