British Prime Minister Boris Johnson announced Monday a four-week delay to the final step of England's roadmap out of COVID-19 restrictions until July 19, amid a surge in cases of the Delta variant. We all must hold our nerve that little bit longer as our vaccine rollout continues and I urge everyone to keep observing hands, face, space and fresh air, and make sure you receive both doses of the vaccine for the best possible protection, he said.
The Delta variant has been spreading rapidly in the country since last month.
The data suggested cases were doubling every 11 days.
The latest Office for National Statistics (ONS) figures show that around one in 520 people in private households in England had Covid-19 in the week to June 12.
