London has recorded no new cases of coronavirus for a full 24 hour period, the latest official data shows.
Public Health England data shows that none of the Covid-19 swabs taken in the capital on Monday came back positive.
It was a fall from 19 cases the previous day.
Officials put the steep decline down to a technical hitch in the patient notification system over the weekend, with NHS England confirming it "did not operate for a period of time" on Saturday.
But the latest data is the first sign that the capital, which was ravaged by the virus early on in the outbreak, is starting to see light.
