Reduced representation

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.
