Percy Pig’s US invasion could be called to a halt amid fears that Donald Trump’s tariffs could affect sales of Marks & Spencer’s popular confectionery brand which has just launched in Target stores across the Atlantic.

Archie Norman, the chair of M&S, has described Percy as the retailer’s “gift to America” but he told the Retail Technology Show in London that “we might have to change our minds” as Trump imposes additional taxes on imported goods. While M&S is not considering withdrawing the sweets, tariffs could push up prices and make them less popular.

The pink confectionery which sells more than 18m bags a year in the UK and is apparently enjoyed by celebrities including Adele and Olivia Rodrigo, went on sale in the US on 30 March both in Target stores across the US and on its website in what was described as Percy’s “biggest journey to date”.
