“We know that things will get worse before they get better,” Johnson is quoted as saying in the letters, the text of which was released by the Downing Street in a statement. “But we are making the right preparations, and the more we all follow the rules, the fewer lives will be lost and the sooner life can return to normal,” he further states in the letter.

He then goes on to urge the people to stay at home, ‘protect’ the National Health Service (NHS) and ‘save lives.’

The UK on Saturday recorded 260 confirmed cases of coronavirus, its highest single-day tally, taking the total number of positive cases in the country to 17,089, including 1,019 deaths.
