The 1903 Preston by-election was held on 14 May 1903, following the death of the incumbent Conservative MP Robert William Hanbury.[1] The by-election was won by the Conservative candidate John Kerr.[2] This was despite the support lent by the Liberal Party and local temperance movements to John Hodge the Labour candidate.[3]
