COVID live UK news: Almost a third of cases in London are now Omicron – as Downing Street cancels its Christmas party | UK News

The Omicron variant is growing “rapidly” in all regions of England and it is spreading faster than Delta, the latest data from the UK Health Security Agency (UKHSA) has revealed. 

Omicron is expected to be the dominant variant in the UK by the middle of this month, it said. 

Experts also estimate that if it continues to grow at the current rate, we could see up to one million cases in total by the end of the month. 

A previous version of the press release issued by the UKHSA said the UK would see one million infections a day, but they have since corrected this to one million in total. 

However, Dr Mary Ramsay, head of immunisation at UKHSA, said the early estimates “should be treated with caution”.
