Apparently, the Queen will be attending services at Crathie Kirk when she goes to Balmoral, but will probably be wearing a mask. I'm not quite sure why "the Queen will probably wear a mask to church" needs to be in the news, but, hey, maybe pictures of Her Majesty wearing a mask will make people realise that masks are for everyone's safety.
I dont think she's been seen wearing one, so Its probably because of that that i t is a news item
