Supermarket bosses including Tesco and Sainsbury’s have urged Brits not to panic buy as a second coronavirus wave threatens another nationwide lockdown.

Big chains are desperate to avoid panic buying - an issue all stores had the first time the UK shut up amid the pandemic.

Essentials like toilet roll, flour and pasta flew off of shelves in March and big chains have assured their customers there is plenty of stock to go around.

Shops have also increased delivery slots, should people need to self-isolate and not make it into their local supermarket.

According to the Mirror, Tesco has more than doubled its online delivery slots to 1.5million from 600,000 during the pandemic.

Sainsbury's have also said there is "high demand", while Ocado said its home deliveries now have a three day waiting list.

People are already shopping for Christmas, with Sainsbury's claiming searches for festive items like puddings have quadrupled in the first two weeks of September.

One supermarket worker told the Mirror: "Some people are definitely panic buying again. We have 4,000 more items this weekend than we usually would.

"We have seen an increase in people over the last few weeks.

"When the panic buying started months ago, we hadn’t experienced it. We are prepared now."

One Twitter user said: "One of the girls in work told me it was going on and they were running out of toilet roll at Asda.

"I hope people don’t start to panic buy, it just makes it worse for everyone."

A 92-year-old woman said: "It is crazy – I’ve lived through a lot and you won’t catch me panicking."
