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.
The main changes are the creation of a new seat in Derbyshire (Derbyshire Mid), and another in Warwickshire (Kenilworth and Southam) which are calculated to be Conservative.
