The worst day of the UK coronavirus pandemic is likely to be Easter Sunday April 12, a source familiar with government emergency talks told Reuters.
A supposedly better scenario under the circumstances would be 20,000 dead, the source said.
However, if the British do not isolate themselves, a worse scenario of 50,000 dying people could happen.
As things stand, the United Kingdom is not on the verge of causing deaths of this magnitude.
A Downing Street spokesperson declined to comment immediately.
The number of coronavirus deaths in the UK rose 24% in one day to 2,921 on April 1.
Scotland and Wales have reported additional cases since the Department of Health’s daily update bringing the total to 2,977.
The latest deaths include a 22-year-old and a 100-year-old, with almost 34,000 people testing positive for Covid-19 in the UK.
England recorded the most deaths (2,698), followed by Scotland (126), Wales (117) and Northern Ireland (36).
It took 19 days for the death toll in the UK to drop to 300. It took an additional 10 days to reach just under 3,000.
Stephen Powis, medical director of the National Health Service England, said on Sunday that the UK would be fine if it kept the coronavirus death toll below 20,000.

According to a study by Imperial College last month, if no action had been taken, the epidemic would have caused more than half a million deaths in Britain and 2.2 million in the United States.
Worldwide, coronavirus deaths have reached more than 47,000, according to a Reuters count.
