West Suffolk MP Nick Timothy breached the code after he failed to declare a relevant financial interest when submitting four written parliamentary questions in December 2025. He said: "I am an honorary member of the Jockey Club Rooms, which provides accommodation and function rooms in Newmarket. "It is an offshoot of the Jockey Club, and I accepted the membership to support a valued local institution. "The parliamentary commissioner for standards accepted that I tabled the questions because of their relevance to the local economy, and understands that my error was inadvertent. Bury St Edmunds and Stowmarket MP, Peter Prinsley was also the subject of an inquiry into a potential breach of the MPs' code of conduct, but no action was taken against him.
