Health Minister Edward Argar gave the update to BBC Breakfast on Wednesday morning.

"I understand he is comfortable, he's stable, he's in good spirits, (and) while he's had oxygen, he hasn't been on a ventilator," Argar said.

No further updates on Mr Johnson's condition are expected until later on Wednesday.

Meanwhile, Argar told the programme:

• "The evidence isn't yet there that will allow us to make a decision" on when the UK night begin to lift current restrictions
• He said the UK needed to "be a little bit cautious" about the reasons for lower deaths rates being reported in Germany
