By coincidence, there are two unrelated Fletchers at the heart of the Corbyn operation (the other one is Simon: see below). Both come with experience of beating the Labour establishment – Kat was elected NUS president in 2004 against opposition from the more centrist Labour Students group. She has been close to Corbyn for close to a decade and was his agent in this year’s election. She is also a power player in Islington politics in her own right, rising to deputy mayor just two years after being elected as a councillor. Outside politics, she runs a small chain of gastropubs called Handmade Pubs.
