Because of the problems of voter confusion and a high number of spoilt ballots in 2007 due to holding Scottish parliamentary and local elections simultaneously and under different voting systems, the next Scottish local elections were held in 2012 instead of 2011. This policy decision was contradicted, however, by the staging of the Alternative Vote referendum on 5 May 2011 as well. Labour MP Ian Davidson expressed opposition to the referendum being staged on the same date as other elections. Scottish Secretary Michael Moore stated that having the referendum on another date would cost an additional £17 million.
