Dan, who is also the South Yorkshire Mayor, has used his own powers to ensure that residents wear masks in Barnsley Interchange - despite the government scrapping the requirement on Monday.
He said: “This is the highest number of new infections in months - it’s clearly not the time to stop wearing masks.
“The government must reverse its decision to remove the legal requirement on Monday.
“Masks are a cheap and effective way to limit the spread of the virus.
“I’m sure it would be more reassuring for the vulnerable, and less challenging for staff, if the government simply kept the legal requirement in place.
“I urge everyone in Barnsley to wear a mask if you can, and make sure you get both your vaccinations.”
