Covid-19 rules and measures are still in place in the UK's supermarkets, with lockdown now four weeks away.
The UK was set to remove Covid-19 restrictions on Monday June 21, but Boris Johnson's Government chose to delay the end of lockdown by four weeks, to Monday July 19.
Even if lockdown does end in July, supermarkets may choose to retain some of the measures they have brought in to protect customers and staff during the coronavirus pandemic. At the very least, we can expect to see them for the next four weeks.
Some of the measures introduced during the height of the Covid crisis have been relaxed. Tesco, for example, no longer asks customers to follow a one-way route, and door greeters have disappeared from some supermarkets.
Below, we take a look at some of the Covid-19 rules for shoppers and safety measures in place in UK supermarkets.
