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.
Within Merseyside, Labour loses one seat which disappears (Knowsley North and Sefton East) and another (Wirral West) to the Conservatives. In Lancashire, the Conservatives lose a seat to Labour (Lancaster and Fleetwood), but gain one new seat (Wyre and Preston North).
