Wider surge testing has been rolled out in five west London boroughs due to a surge in coronavirus cases linked to the Indian variant.

 From Monday, testing in Ealing, Hillingdon, Brent, Harrow, and Hounslow will begin.

It will target secondary schools and PCR tests will be offered to everyone else in the areas who do not have symptoms.

Cases of the new variant in west London have increased from 400 to 720.
