A hospital in British Prime Minister Boris Johnson's west London constituency said it had closed to emergency patients after an outbreak of coronavirus.

The outbreak was declared last Friday at the Hillingdon Hospital.

As of yesterday, 70 members of staff were self-isolating, "a number of whom" have tested positive for the virus, a spokesman for the NHS trust said.

"As a result, the trust has taken the precautionary decision to close Hillingdon Hospital to emergency ambulances and emergency admissions," he said.

The British government has recorded more than 44,000 deaths in patients confirmed to have coronavirus, the highest toll in Europe, with official statistics showing the toll could be far higher.

A lockdown imposed in late March is being eased but Mr Johnson - who spent a week in hospital himself with coronavirus - says he will act quickly to shut down localised outbreaks.

The hospital serves the Mr Johnson's Uxbridge and South Ruislip constituency.

Mr Johnson sent a video message to staff at the hospital to mark International Nurses' Day in May.

He thanked them for their care when he was "idiotic enough to get a shard of coffee pot in my foot".
