UK Prime Minister Boris Johnson has tested positive for the coronavirus and will self-isolate for seven days.

The prime minister announced the news on Twitter on Friday morning, saying he had a cough and a temperature on Thursday afternoon.

A representative for Johnson insisted on Friday that the prime minister would remain in his post and continue leading the UK’s response to the coronavirus crisis via teleconferencing.

Here’s what would happen if Johnson became too ill to remain prime minister.

Who is Johnson’s ‘designated survivor’?

For now, Johnson will remain in his post. But the prime minister has made the UK’s foreign secretary, Dominic Raab, his “designated survivor” should he become too ill, The Sunday Times reported over the weekend.

Raab, who has twice tested negative for the coronavirus, would become the de facto prime minister while Johnson received treatment.

The decision to give Raab the job reportedly upset some other members of Johnson’s Cabinet.

One unnamed minister told The Times: “If Boris can’t do his job because he is incapacitated, a lot of people think that Michael [Gove] should be running the show, not Raab. One of these people is Michael, of course.”

Should Johnson become too ill to remain prime minister, Raab would step in.

As the UK is a parliamentary democracy, there would be no need, under the UK’s unwritten constitution, for an immediate election. However, political pressure from the opposition could eventually lead to one.
