Westminster City Council said it had seized about £474,000 of counterfeit and illegal goods from American candy and souvenir stores in the past six months, including unsafe vapes.

A spokesperson added "very few" of the shops were "serving sufficient customers to be commercially viable".
"Instead, we believe that these properties are used to avoid business rate bills and possibly commit other offences."
