West: New Constituency Boundaries 2006

Each new seat can be described as a combination of parts of old seats. These table show this decomposition. The winner of the old seat at the 2005 election is shown by party colour, as is the implied winner of the new seat.

The implied results are now calculated using the local election results for the wards which make up each old seat. This should be more accurate than the earlier implied results which assumed each constituency was homogeneous.

In Bristol a new seat is created (Filton and Bradley Stoke) which is expected to be Conservative. A new seat is created in Wiltshire (Chippenham) which should be Lib Dem.
