Some shops will have to close, but don't panic buy - BRCpublished at 08:58 British Summer Time 22 July 2021
Some food retailers will be forced to close due to isolating staff, the head of the British Retail Consortium has warned.
Helen Dickinson tells BBC Breakfast that some areas of the country have been harder-hit than others - and business owners are getting increasingly anxious about how they will cope.
She says 16 August - when the rules to self-isolate following contact with someone who is positive - "feels a long time away".
"Everybody I am talking to is seeing absence rates that are higher than they would normally expect.
"They are already taking mitigating actions, which include changing shifts, reducing hours and, in some cases, needing to close stores."
Shoppers might get less choice in supermarkets, face longer waits for deliveries or find opening hours of local stores are reduced.
And she adds: "There will be many smaller businesses where if they only have one or two staff and they need to self-isolate, then that's them needing to close their doors completely."
But Dickinson emphasises: "What is the most important thing is that people don't panic because there's no need to panic, because there's plenty of food in the country."
