The UK's coronavirus hospital death toll has increased by 315 with one of the victims aged only 17.
England reported 279 new fatalities, Scotland had 33, Northern Ireland recorded two and Wales had one.
It is the lowest daily increase on a Tuesday since 263 fatalities were reported on November 3 and about a 30 per cent drop on last week's total.
The tolls announced on recent Tuesdays were 437 on February 23, 540 on February 16, 583 on February 9 and 860 on February 2.
Of the latest fatalities in England, one was a 17-year-old with no underlying health conditions, with the patients aged between 17 and 102, NHS England said.
There tends to be a spike in the daily death toll on Tuesdays due to a lag in reporting fatalities at the weekend.
The latest figures were announced as as many as six in ten people who've had Covid-19 could be vulnerable to catching it again from the new Brazil variant that was recently discovered in the UK.
