A map has revealed which specific areas in south east London are worst affected by coronavirus.
The tool highlights coronavirus hotspots across the area by colour coding them according to the infection rate.
The map displays weekly data from March when the pandemic began.
The latest data is for the week leading up to October 25.
It shows the rate of infection in each area and where positive cases have been confirmed in recent days.
It is based on pillar 1 and pillar 2 testing data from Public Health England.
Areas are then colour coded based on the infection rate.
Seven-day rates are expressed per 100,000 population. They are calculated by dividing the seven-day count by the area population and multiplying by 100,000.
Here are the hotspot areas, where infection rates are over 200 per 100,000:
Lesney Farm & Colyers East (Bexley) – 299.4 cases per 100,000
Bickley West (Bromley) – 280.5 cases per 100,000
Chislehurst East & Hoblingwell Wood (Bromley) – 241.9 cases per 100,000
Elmers End (Bromley) – 233.2 cases per 100,000
Anerley South (Bromley) – 201.4 cases per 100,000
Infection rates are significantly lower in Greenwich and Lewisham, where no single area has breached the 200 mark.
In Lee, for example, the figure is currently at 39.6 per 100,000.
The majority of south east London is currently in the 100-200 per 100,000 range, below the national average of 225.9.
Nonetheless, Boris Johnson is expected to announce plans for a national lockdown in England at a press conference this afternoon.
The Prime Minister is expected to be joined by Professor Chris Whitty and Sir Patrick Vallance in Downing Street at 4pm, following a meeting of his Cabinet earlier in the afternoon.
Mr Johnson has so far resisted pressure to introduce nationwide restrictions, opting instead for a localised tier system, but he is reportedly considering closing everything except essential shops and education settings for a month from Wednesday.
The policy shift comes after new data showed the extent of cases across England. The Office for National Statistics estimated that 568,100 people in households were infected with coronavirus in the week ending October 23.
Members of the Government’s Scientific Advisory Group for Emergencies (Sage) have backed the introduction of more stringent measures.
