And who exactly will enforce this in a city the size of London?
The government has lost control, failed to plan and is simply repeating the same mistakes over and over and people no longer trust them.
So good luck with policing the capital...
They should be focusing on getting testing/track and trace to work, build more capacity for the health service and better quarantine measures for people coming back from abroad.
Lockdown did not work and the government failed to use it to put the above tools in place.
So I am not listening to anything they have to say anymore.
Johnson and his cronies should resign and a temporary government with cross party representation should take over.
