The gap between the UK's official Covid-19 figures and the likely true number of cases in the country is getting wider, new analysis shows.
An average of 99,900 cases of coronavirus per day were recorded from January 23-29, according to the Government's Covid-19 dashboard.
But the true total was likely to three-and-a-half times this figure, at 357,200 a day, according to estimates published on Friday by the Office for National Statistics (ONS).
