Almost a third of the 42 Britons who have so far died from the Indian (Delta) Covid had been double jabbed, a new report has revealed.

With the Prime Minister on the verge of delaying 'Freedom Day' by up to four weeks, new analysis by Public Health England (PHE) has revealed that 29 per cent of Covid deaths from the B.1.617.2 strain had received two injections.

And, in a further blow, the PHE report suggests the Delta variant has a 64 per cent increased risk of household transmission compared to the Kent (Alpha) variant.

It is also believed to be 40 per cent more transmissible outdoors, according to the PHE figures.

The Delta strain is now the UK's most dominant, with more than 90 per cent of Covid cases in the UK now the Indian variant, according to PHE.
