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 that the old seat of Eccles (Labour) disappears. The new seat of Rochdale is now predicted to be a Lib Dem hold.
