Frank Field, Baron Field of Birkenhead

Field represented Birkenhead for forty years and turned his casework into national policy: constituents' experiences of benefit delays drove his campaigns on hunger, and he set up Feeding Birkenhead to provide holiday meals for local children and research the causes of food poverty. He also helped found the Birkenhead foodbank partnership. When he left Labour in 2018, many constituents still voted for him as an independent in 2019, though not enough to keep the seat.
