Laws in England requiring masks to be worn in shops and other indoor settings lapse early Monday, as will capacity limits in bars and restaurants, and rules limiting the number of people who can socialize together.
Britain aims to accelerate its economic recovery. But that ambition could be thwarted, with the tens of thousands of new infections daily forcing hundreds of thousands of workers to self-isolate.

New cases nationwide surged 70% in the past week, from the prior seven days, to an average of 30,000 per day, fueled by the delta variant. Deaths rose 26% to an average of 250 daily, mostly in unvaccinated patients.
Murthy blames social media companies for fueling misinformation and false narratives about the safety and effectiveness of COVID-19 vaccines, echoing President Joe Biden's comments that such companies are "killing people."

10:17 p.m. Vietnam announces it will impose restrictions on movement in 16 southern provinces for two weeks from Monday as the country faces its worst COVID-19 outbreak so far.
The country has managed to keep coronavirus cases relatively low due to targeted mass testing and strict contact tracing, border controls and quarantine measures, but new clusters of infections in recent weeks have triggered concern among health officials.
"The current outbreak we are facing is getting more complicated," the government says in a statement. "The curbs are to protect people's health."
9:45 p.m. British health minister Sajid Javid tests positive for COVID-19, but says his symptoms are mild and he had two doses of vaccine against the disease.
