The UK’s new Prime Minister, Andy Burnham, wants to make British business great again. Many of Britain’s corporate crown jewels make more of their money in the US and fast-growing Asian markets than at home. Even consumer goods giant Reckitt Benckiser, with nearly 200-year-old roots in the UK, got two-thirds of its 2025 revenue from emerging markets and North America. Burnham’s predecessors and his peers in Germany and France have similar ambitions, and their own headwinds to deal with. Good luck, Mr. Prime Minister.
