Protesters occupy Mayfair bookshop over Irish land-rent increases

On 2026-04-04, Sinn Fein-backed protesters occupied Heywood Hill bookshop in Mayfair, central London, to challenge the Duke of Devonshire over steep land-rent increases for sheep farmers in County Waterford, Ireland. The sit-in was directed at the shop’s owner, Peregrine Cavendish, rather than involving reported physical violence. No fatalities were reported.
