Finally a definitive statement from Downing Street for all those Hunsnetters frothing that people 'aren't allowed' to buy cake or cucumbers or whatever is wedging their knickers:
Downing Street said shops that are allowed to remain open during the lockdown are free to sell whatever items they have in stock.
Asked about the idea of police patrolling particular supermarket aisles to see what people are buying, the prime minister’s spokesman said:
"We set out a list of shops which could remain open and if the shops are on that list then they are free to sell whatever they have in stock. Obviously provided it’s legal to do so."
