As Piggy said, who knows what with today.
But staying further in the past where info likely better - Looks like 21st was a second peak for London. To me that still implies it's all driven by the weekend socialising at the minute, but it could also be less testing in the last couple of days, however LFD positives still high, but who knows possibly how much higher they would have been.
I think rest of the country not enough to say with the unsureness of the data nearer the time where we should be seeing fastest growing.
Quite a bit of hospitalisation growth in the days since christmas in England - too soon for christmas spreading, and could be different discharge / type of admission, or could be faster growth? No growth in ventilation beds yet (as in it's still lower than before omicron arrived despite a month of omicron growth)
