Exhausted and overworked staff at a London hospital featured on the documentary 24 Hours in A&E have been caught sleeping on the job, it was revealed yesterday.

Staff at King's College Hospital, made famous by the Channel 4 documentary, are so stretched that they have been catching 40 winks during shifts - a that trend is symptomatic of the entire NHS according to the Unite union.

A national newspaper reported having seen an internal document that warned hospital workers: "There have been a number of recent incidents where staff have been found asleep on duty, or it has been reported that staff have been asleep on duty."
