The UK government is reviewing the tiered lockdown allocations for different parts of the country as scheduled by law on Wednesday, even as millions of more people in and around London moved into the highest alert level of Tier 3 coronavirus restrictions after a worrying spike in infections.

With the addition of the UK capital and surrounding areas of Essex and Hertfordshire to Tier 3, or near-complete lockdown, around 61 per cent of England’s population is now living under the toughest lockdown rules which impose a ban on inter-household mingling indoors and a closure of all restaurants and bars except for takeaways and deliveries.

The number of COVID-19 cases in London has increased significantly over the past two weeks and we continue to experience the highest case rates of anywhere in the country, said Professor Kevin Fenton, London Regional Director for Public Health England.

We are now in a situation of exponential growth which, if left unchecked, would lead to a rapid escalation in cases and hospitalisations that could overwhelm our NHS (National Health Service) services over the festive period and into the New Year. Whilst no-one wants to see London under tighter restrictions, the stark reality of the situation means we have no choice, he said.
