A British government minister says Prime Minister Boris Johnson has spent the night in the intensive care unit of a London hospital, but is not on a ventilator.

Cabinet Office Minister Michael Gove said, while Johnson is not on a ventilator, he is being given oxygen. Gove said Johnson is "receiving the very, very best care from the team at St Thomas' and our hopes and prayers are with him and with his family."

Johnson was admitted to St. Thomas' Hospital late Sunday, 10 days after he was diagnosed with COVID-19.

He was the first major world leader to be confirmed to have the virus.

He was moved to the ICU Monday after his condition deteriorated.
