London: British Prime Minister Boris Johnson will be back at work in 10 Downing Street on Monday, after recovering from the novel Coronavirus infection.

The prime minister, 55, was admitted to hospital in London with "persistent symptoms" of the infection.

Johnson told his cabinet colleagues that he will be back to his normal schedule following his treatment in St. Thomas' Hospital in London for COVID-19.

Johnson said on April 12 that he had left the hospital "after a week in which the NHS has saved my life, no question."

Johnson, who spent three nights in intensive care in the hospital, spent a week in Chequers, the prime minister's country house after leaving the hospital.

The UK's Prime Minister Boris Johnson, who spent more than three weeks out of action after testing positive for coronavirus, is expected to resume his duties from Monday.

British Foreign Secretary Dominic Raab, who is also the first secretary of state, was deputized by Johnson to carry out his duties during his illness.

Johnson's return would be a "boost for the country", Foreign Secretary Dominic Raab, who has been standing in for the Prime Minister in his absence, said on a BBC interview.

Johnson is "raring to go", he added.

Asked whether he had enjoyed the experience of temporarily running the country, Raab said this "did not do justice" to the task he had been faced with and his thoughts throughout had been with Johnson and his family, "particularly when we knew it was touch and go".

However, last week he spoke to the Queen and US President Donald Trump, and also met senior ministers to discuss the next stage of the UK's response to the pandemic.
