The mayor of London said the NHS and emergency services have “gone above and beyond during an extremely testing period” and everyone who followed the rules has “played in part” in reducing the pressure health services faced.
“But the virus and the Omicron variant is still with us and daily infection rates are still too high. That’s why we must all remain vigilant and continue to do the things that have allowed our city to reopen safely,” Mr Khan added.
He went on to call on the government to “rethink” its plans to remove the mandatory wearing of face masks.
“Wearing a face covering remains one of the single most important and easiest things we can all do to prevent the spread of Covid-19 and that’s why I’m renewing my calls for the government to rethink their plans and keep legislation in place to make them mandatory on public transport,” he said.
