Rugby – one borough but two constituencies
A constituency for Rugby was created in 1885 when Gladstone was prime minister and lasted right the way through to 1979.
In 1983 when Margaret Thatcher was prime minister Rugby was torn apart with part of the borough being represented by the MP for Nuneaton whilst the rest of Rugby was lumped in with Kenilworth.
It was all change again in 2010 when Gordon Brown was prime minister with Rugby once again being split in two (but along different fault lines). Then the southern part of the borough including Ryton, Stretton-on-Dunsmore and Dunchurch was put into the Kenilworth and Southam constituency. The rest of the borough is called the Rugby constituency but contains Bulkington from the Nuneaton and Bedworth district council area.
None of this messing around with constituency boundaries has done anything to make the results of general elections any more representative of how people voted - see http://rugbylibdems.org.uk/en/article/2014/973728/the-boundary-commission-fails-warwickshire .
