Three Surrey areas have infection rates which exceed 500, latest figures show.
Previously, only Waverley had escaped the tightest rules and remained in Tier 2. However, on Wednesday (December 23) health secretary Matt Hancock confirmed the news, following concerns over new mutant variant of coronavirus in London and the south east.

In Tier 4, residents essentially face the same restrictions as they did during the November lockdown. Those in Tier 4 are asked to stay at home, unless they have a reasonable excuse, with all non-essential shops being forced to closed. Hairdressers and indoor entertainment venues must also shut.
Residents are not permitted to meet with other households indoors, unless in their support bubble, and outdoors they can only meet with one other person from a different household.
Across the county, infection rates continue to climb. Spelthorne, Tandridge and Woking have the highest infection rates in Surrey, according to latest figures, with 543.8, 526.5 and 513.9 new cases per 100,000 people respectively.
Waverley still records the lowest rate, but is edging closer to 300 cases per 100,000 people.

The Press Association collates data which gives a rolling seven-day rate of new coronavirus cases for every local authority area in England.
The latest data, released on Christmas Eve (December 24), covers the week up to December 20. Data for the days since has been excluded as it is likely to be revised.
An infection rate is calculated by looking at the number of coronavirus infections per 100,000 people in any given area across the country.
