The surge in coronavirus cases across London is "deeply concerning" and requires further Government action to be brought under control, Sadiq Khan has said.
The Mayor of London wrote to Boris Johnson on Sunday requesting for an immediate increase in Covid-19 testing provision across the capital in response to the rising number of infections.
Mr Khan also asked for a compensation scheme to be put in place for businesses ahead of any further restrictions being imposed on the city.
He warned that moving London from Tier 2 into Tier 3 would have a "catastrophic" economic impact on businesses and put "hundreds of thousands of livelihoods at stake".
