Disenfranchised and rotten boroughs
The following 56 Parliamentary Boroughs, in England, were completely disenfranchised by the Act. They had all returned two members except for Higham Ferrers, which was a single member constituency. The disenfranchised boroughs lost all independent legislative representation; instead the inhabitants could vote only as part of the county electorate.
Halved representation
The following thirty boroughs were reduced from two MPs to one. The applicable county or well-recognised part of a county in 1832 (in the case of the Ridings of Yorkshire and the Isle of Wight, which was part of Hampshire) is given. Some places were moved to other administrative counties in the 1973-74 local-government changes—e.g., Christchurch moved from Hampshire to Dorset.
Weymouth & Melcombe Regis, Dorset had jointly elected 4 MPs; this was reduced to 2.
