Letter from Colin Mowl, dated 5 June 2007:
The National Statistician has been asked to reply to your question concerning what the (a) actual and (b) percentage change in the size of the electorate in each parliamentary constituency was between the last two years for which figures are available, grouped according to region and listed in descending order according to percentage change. I am replying in her absence. (140143)
The attached table shows the actual and percentage change for parliamentary electors by parliamentary constituency between 1 December 2005 and 1 December 2006 and are sorted by percentage change in descending order by UK Country and Government Office Region in England. A copy of the table has been placed in the House of Commons Library.
