Boris Johnson appeared at the Downing Street press briefing with Professor Chris Whitty, the chief medical officer for England, and Sir Patrick Vallance, the chief science adviser.

Omicron, which was designated a "variant of concern" by the World Health Organisation, has been detected in Nottingham and Brentwood.

The latter was linked to the Nottingham case, which itself is linked to travel to South Africa.

However, it is unclear when the two people became infected or what their full travel history is.

The UK is the second European country, after Belgium, to have found a case in its borders.
