Covid-19 infections have risen sharply across most of the UK and are nearing record levels in England, while both Scotland and Wales have reached an all-time high, new figures show.
Across the UK as a whole, 4.26 million people were likely to have had coronavirus last week - just short of the 4.30 million in the first week of 2022, which was the highest total since estimates began.
Infections in Northern Ireland, however, are believed to be falling, with levels having dropped for two weeks in a row, according to the UK Office for National Statistics (ONS).
Infections have fallen for the second successive week and now stand at an estimated 108,700 people, or one in 17, down from 130,600 people, or one in 14.
