Britain's biggest supermarket Tesco will prevent customers from bulk buying flour, pasta, toilet roll and anti-bacterial wipes to prevent a re-run of the Covid-19 stockpiling that stripped shelves bare earlier this year.

With Covid cases rising once again in Britain, Prime Minister Boris Johnson told people to work from home if they can earlier this week, prompting Tesco to join smaller rival Morrisons in reimposing restrictions.

Both chains have also placed staff at the entrance to stores to ensure that face coverings are worn. “We have good availability, with plenty of stock to go round, and we would encourage our customers to shop as normal,” a spokeswoman said, Reuters reported.
