Professor Graham Medley from the London School of Hygiene & Tropical Medicine and a member of the Scientific Advisory Group for Emergencies (Sage) advising the Government was speaking to BBC Radio 4’s Today programme.

“The newer Delta variant is now quite common around the globe so it would have ended up in the United Kingdom at some point but perhaps it would have been delayed.

“It’s really the competition between the virus and the vaccine so had the variant arrived in the country when we’d had more people vaccinated, then it may well not have grown in the same way that it has.

“It is now the predominant virus in the United Kingdom. And so it got a good start. A lot of cases introduced,
