What is "selsdon"

Selsdon is an area located in South London, England in the London Borough of Croydon. The suburb was developed during the inter-war period during the 1920s and 1930s, and is remarkable for its many Art Deco houses. It is also well known for the Selsdon Park Hotel, the venue of a 1970 meeting of the Conservative Shadow Cabinet to settle the party manifesto for the impending general election. Labour Party leader Harold Wilson coined the phrase Selsdon Man to describe the free market approach which was agreed, and the Selsdon Group was later formed within the Conservative Party to campaign for its retention.
