The 48-year-old is said to have developed these over the weekend.

While self-isolating he is expected to keep in touch with Downing Street colleagues remotely.

Health Secretary Matt Hancock has also contracted the virus .

While Chief Medical Officer for England Chris Whitty is self-isolating due to symptoms, as is Scottish Secretary Alister Jack.
