London: New Constituency Boundaries 2018

Each new seat can be described as a combination of parts of old seats. These tables show this decomposition. The winner of the old seat at the 2019 election is shown by party colour, as is the implied winner of the new seat.

The implied results are calculated using the local election results for the wards which make up each old seat. This should give the most accurate projection, since it reflects varying political behaviour across the seat.

London Change Table

The table shows how the various changes affect each party in this area. The total old and new seats are shown for each party, as well as their difference ('Change'). The change in seats is also explained through the four explanations:

• Disappear : seats which have disappeared as they are broken into small fragments
• Switch Out : seats lost because their political make-up has altered
• Switch In : seats gained because their political make-up has altered
• Fresh : freshly created new seats which are made up of small fragments of old seats

The old seats which are disappearing are: Chelsea and Fulham; Dulwich and West Norwood; Erith and Thamesmead; Finchley and Golders Green; Hackney North and Stoke Newington; Leyton and Wanstead; Poplar and Limehouse.

The old seats which are lost to another party are: Croydon Central; Eltham.

The new seats which are gained from another party are: Croydon South East; Eltham and East Wickham.

The new seats which are freshly created are: Leyton and Stratford; Shoreditch and Bethnal Green.
