Political career 
Between 1981 and 1990 Daniel Finkelstein was a member of the SDP, becoming Chair of the Young Social Democrats on the defection of his predecessor Keith Toussaint to the Conservative Party during the 1983 general election campaign. Subsequently he was elected youth representative on its National Committee, a Parliamentary candidate (Brent East 1987) and a close ally and adviser to David Owen, the SDP leader. When merger with the Liberal Party was proposed, Finkelstein was one of the leading opponents and refused to join the merged party. After Owen had announced his resignation from politics, Finkelstein was the spokesman for a group of young SDP members who joined the Conservative Party.
Before working for the Conservative Party, Daniel Finkelstein was Director of the think tank the Social Market Foundation for three years. During his period with the SMF the organisation brought New York police commissioner Bill Bratton to London, for the first time introducing UK politicians to the successful new strategies being used there.
Conservative Party 
Between 1995 and 1997 Finkelstein was Director of the Conservative Research Department and in that capacity advised Prime Minister John Major and attended meetings of the Cabinet when it sat in political session. Finkelstein became among the earliest advocates of the 'modernisation' of the Conservative Party, laying out the principles of change in a series of Times columns and speeches.
Between 1990 and 1992 he was the editor of Connexion, Britain's first internet and data communications newspaper. Finkelstein joined The Times in August 2001 as part of the leader writing team and was Comment Editor from March 2004 - June 2008. He became Chief Leader Writer in June 2008. He began The Times blog Comment Central in September 2006. He is also a regular columnist in The Jewish Chronicle. His weekly football statistics column, the Fink Tank, began in 2002 and runs in The Times on Saturdays.
Finkelstein was given an Award of Doctor of Science honoris causa by City University London in 2011.
