The UK Prime Minister Boris Johnson has broadcast on Twitter his personal thanks to the staff who saved his life.

Described by veteran journalist Andrew Neil as an "unprecedented broadcast by a British Prime Minister" the very poignant video was shot shortly after being discharged from hospital.

He says; "It is hard to find the words to express my debt to the NHS for saving my life."

He adds a plea for everyone to stick to social distancing rules.  "The efforts of millions of people across this country to stay home are worth it. Together we will overcome this challenge, as we have overcome so many challenges in the past."

He also thanks by name many of the doctors and nurses who saved his life, especially Jenny from New Zealand and Luis from Portugal.

His partner Carrie Symonds in a separate tweet says: "I cannot thank our magnificent NHS enough. The staff at St Thomas’ Hospital have been incredible. I will never, ever be able to repay you and I will never stop thanking you."
