Nadhim Zahawi today tried to quell a backlash from local leaders on plans to drop mandatory masks on public transport, as a poll found 50 per cent of Britons want 'Freedom Day' delayed.

The vaccines minister insisted people will still be 'expected' to wear coverings in confined space spaces under new guidance being issued this week, even though the legal compulsion will go.

But he insisted that the unlocking schedule was set to go ahead as planned on July 19 - with Boris Johnson due to give more details at a press conference tomorrow. 

'We're seeing a rise in infection rates in this country, but also in Europe and elsewhere.

The difference for us is that the vaccination programme has been so successful,' Mr Zahawi said. 

The comments came after Manchester Mayor Andy Burnham warned July 19 could turn into 'anxiety day', complaining that face coverings should remain a legal requirement.

Meanwhile, Sadiq Khan is still considering a bid to force passengers to keep wearing masks on trains, Tube and buses in London.   

The level of nerves among the wider public was demonstrated today as research by Opinium found half would prefer the unlocking slated to happen a week tomorrow to be delayed.
