Although these are the results after the election, the number of seats per party changed later that year.

However, after the 2006 election, he left the party and joined the English Democrats Party. Also this year, Councillor Nicholas Yates, who had been returned by the Brighouse ward in the 2004 election for four years and is included in the twenty Conservative seats shown below, left the party to continue his tenure as an Independent. This left the Conservatives with 18 seats, 1 held by the English Democrats and 4 held by Independents. In December 2006, Illingworth and Mixenden ward Councillor Tom McElroy (Labour) died suddenly, leaving Labour with nine seats. The by-election to succeed him took place on 22 February 2007, with Labour holding the ward.
