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 change is in Birmingham, where one Labour seat disappears. Although its name survives, Birmingham Selly Oak is the most fragmented old seat.
