Shoppers in England lined up outside stores across the country on Monday, as many non-essential retail outlets opened for the first time since March.
People formed long, socially-distanced queues outside businesses in Oxford Street, one of London's most popular shopping districts.
From Monday, retailers are allowed to open if they comply with the government's coronavirus-secure guidelines, which require customers to shop while keeping 2m apart. Changing rooms in clothes stores remain closed.
This week, as shops start reopening in England, remember to follow social distancing rules to protect yourself and others," UK Prime Minister Boris Johnson said on Twitter.
CNN's Anna Stewart said many of those she had spoken to outside the Apple Store on London's Regent Street were seeking repairs or returns, rather than shopping for new products.
Businesses are bracing for dramatically lower footfall than before the Covid-19 pandemic began.
Bars, restaurants and pubs remain closed across the UK.
The UK has recorded more than 297,000 cases of coronavirus, according to Johns Hopkins University, making it the worst affected country in Europe.
