British Prime Minister Boris Johnson was released from the hospital Sunday as he continues to recover from COVID-19. In a video message, he thanked the National Health Service staff who took care of him.

Prime Minister Boris Johnson:: “I have today left hospital after a week in which the NHS has saved my life, no question. It’s hard to find words to express my debt.”

This comes as criticism mounts over the Johnson government’s response to the coronavirus crisis, including failure to get enough PPE and tests to NHS workers. Britain’s official coronavirus death toll has now topped 10,000, and officials warned it could end up with the highest number of fatalities in Europe.
