The government was reportedly warned three years ago that the NHS would be quickly overwhelmed in the event of a severe disease outbreak.
A major exercise testing the UK’s ability to deal with a pandemic - codenamed Cygnus - exposed “terrifying” failings, the Sunday Telegraph reports.
Ministers were told that hospitals would rapidly run out of intensive care beds, mortuaries would be overwhelmed and doctors would be forced to deny frail patients critical care.
A classified report on Cygnus’s findings - which has never been made public - highlighted problems delivering protective equipment such as masks and gowns to health workers, an issue which has been frequently raised by medics battling Covid-19.
