Mayor of London Sadiq Khan has said the city is "two weeks behind" parts of the UK which have seen tighter coronavirus restrictions enforced.
Speaking in central London on Friday, the mayor said he is "really worried" about the rising number of cases in boroughs across the capital.
We're looking into all possibilities in London and we're looking to see which policies across the country are successful. According to the latest evidence I've seen we're about two weeks behind some parts of the country.
The Mayor urged Londoners to follow the advice on social distancing.
