He fought Lewisham East in the February 1974 general election, coming second to Labour's Roland Moyle.

Marshall served as a councillor in Aberdeen from 1968 until 1970 and then in Ealing from 1971 until 1986.

He was MEP for London North from 1979 to 1989.

He lost to Michael Portillo in the selection for the Enfield Southgate byelection in 1984, but was later selected for Hendon South in the London Borough of Barnet and became Member of Parliament for that seat at the 1987 general election. He served as PPS to Tony Newton, when Newton was Leader of the House of Commons.
