More supermarket chains have relaxed rules on the number of products customers can purchase.

Morrisons and Asda are the latest UK supermarkets to ease restrictions placed on the purchase of items during the coronavirus pandemic.

What are the new rules, and why have they been changed?

Previously, customers at Asda - including those shopping online - were restricted to buying a maximum of three units of any item. This was to ensure that there were enough essential supplies for every customer.

Morrisons had similar limits on the amount of any one item that customers could buy.

However, Asda has now removed limits on chilled products, fruit and vegetables - meaning shoppers are less restricted in what they can buy.

Following suit, Morrisons says it has upped some limits on items from three per customer to four per customer.

In some cases, the supermarket has removed limits altogether in order to make it easier for customers to donate products to food banks in need. Customers will be able to make donations straight after purchasing products in-store, as closed Morrisons cafes are now being used as donation drop-off points.
