PM Boris Johnson has suggested the recent spike in coronavirus cases in the UK is a result of a "fraying of people's discipline" over the summer.
He said compliance with the virus restrictions had been "high at first" but then "probably... everybody got a bit, kind of complacent and blasé".
Cases have increased sharply across the UK since the end of August.
After starting to relax restrictions before the summer, the government has since had to toughen its measures.
It comes as the latest UK figures show there have been a further 6,968 cases and another 66 deaths.
The R number - a measure of how many other people each person with the virus is infecting - has risen to between 1.3 and 1.6.
However, there is
more evidence that new coronavirus infections may be increasing more slowly than in previous weeks.
