Ian David Luder CBE JP (born 13 April 1951)[1] is a former Lord Mayor of London, serving from 2008 to 2009.

Luder was Aldermanic Sheriff of London for 2007–08 and was elected Lord Mayor on 29 September 2008, taking office in the "Silent Ceremony" on 7 November.

Apparently the Luders had refused their neighbours' request to stop feeding the animal, who was overweight and had a heart condition, and in fact had shut the cat in their home for 36 hours while they were away.

[8] In December 2014, Luder was one of five people on the shortlist to become United Kingdom Independence Party (UKIP) candidate for the constituency of South Basildon and East Thurrock at the 2015 general election.

[9] Shortly afterwards, the successful candidate, Kerry Smith, resigned as UKIP's nominee for the seat after he was recorded making offensive remarks about fellow party members in a telephone conversation.
