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.
There have been no major changes to seats in the South East region. Nevertheless small boundary changes to Gillingham and Rainham, Rochester and Strood, Sittingbourne and Sheppey, and Thanet South cause all these four seats to move from Labour to Conservative.
