Christian Tage Forter Wolmar (born 3 August 1949) is a British journalist, author, railway historian and Labour Party campaigner.

Wolmar was educated at Lycée Français Charles de Gaulle, a French independent school in South Kensington, followed by the University of Warwick[1] where he obtained a degree in economics and was editor of the student newspaper, Campus.

[5] Following his graduation from university in 1971, Wolmar worked for Marketing, Retail Newsagent, the New Statesman, and the London Daily News.

[1] In 1976, Wolmar joined the staff of drug users' charity Release, and stopped the use of its office (1 Elgin Avenue, London W9) as a holding address for the PIE, a paedophile activist group.

In September 2012, Wolmar announced his intention to seek nomination for the Labour candidacy at the 2016 Mayor of London elections.

Described by The Londonist as "the non-politician who wants to be mayor",[13] Wolmar spoke at the five official hustings about his campaign vision for a more affordable, liveable and sustainable London.

[9] The campaign persuaded the eventual winner, Sadiq Khan, to push for the pedestrianisation of Oxford Street and to introduce the 'Hopper' fare.

Wolmar was selected as the Labour candidate to contest the Richmond Park constituency in the 2016 by-election and ran on a strongly Remain platform.
