The number of coronavirus deaths in the UK rose by 37 on Tuesday, marking the largest daily increase in over two months.
Data released via the government’s coronavirus tracking website showed that 4,926 new cases were recorded up to 22 September, bringing the total number of cases nationwide to 398,625 so far.
Another 37 deaths were also announced, 26 more than the 11 new deaths reported by the government on Monday.
The increase is the highest since 9 July, when there were also 37 deaths at a time when lockdown restrictions were beginning to be being eased across the UK.
It comes as prime minister Boris Johnson announced a host of new measures aimed at controlling an apparent second wave of the virus.
Johnson warned new coronavirus restrictions could last six months, with office staff working from home, the wider use of face masks and a 10pm curfew on pubs and restaurants.
He said that the new curbs could continue well beyond Christmas and New Year "unless we palpably make progress" in controlling the spread of the virus.
The Prime Minister also announced tougher enforcement measures, with businesses facing fines or closure for failing to comply with coronavirus rules, and people facing £200 penalties for failing to wear masks where required or breaching the so-called "rule of six".
The military could be brought in to free up police officers to tackle coronavirus rulebreakers, the Prime Minister said.
