Vladimir Derer (1919–2014) was a British political activist in the Labour Party who escaped from Czechoslovakia in the late 1930s to live in Britain. For nearly four decades Vladimir was an important leader and strategist in the campaign to transform the Labour Party by making it more democratic and accountable to its members. He helped to form the Campaign for Labour Party Democracy (CLPD) in 1973 and was its secretary from 1974 until 2005. The CLPD is dedicated to introduce constitutional and rule changes and modernise the governance of the Party. Mandatory reselection of MPs and electoral college for the Leader were the most notable of many important democratic reforms implemented from the late 1970s until today.
