London has continued to grow as the UK’s Covid capital with one in 20 people testing positive for the virus last week.
It is the highest proportion for any region in England, according to the Office for National Statistics.
North-east England had the lowest proportion, at around one in 55.
An estimated 1.7 million people in the UK had Covid-19 in the week ending December 19, the highest number since the pandemic began.
A total of 2,097 people were in hospital in London with Covid-19 as of 8am on December 23, according to figures from NHS England.
This is the highest number since February 27 and is up 44 per cent from a week earlier.
During the second wave of coronavirus, the number peaked at 7,917 on January 18.
Across England, 7,114 patients were in hospital with Covid-19 on December 23, the highest number since November 4 and up 11% week-on-week.
The second-wave peak for England was 34,336 on January 18.
Omicron cases are now believed to account for a staggering 90 per cent of Covid infections in London.
The variant, which is believed to evade vaccines to some degree, has swept through the capital with rapid speed in recent weeks.
Research from the UK Health Security Agency reveals that people infected with Omicron are 50 to 70 per cent less likely to be admitted to hospital compared to the Delta variant.
It also found a person who becomes infected with the variant is 31 to 45 per cent less likely to have to go to A&E.
The effectiveness of boosters against Omicron appears to wane after 10 weeks, UK experts warned.
