The rapid population expansion in the area is the principle reason why the boundaries and it means that West Lothian residents will now be in one of three constituencies when voting for Holyrood elections:
- Linlithgow and Bathgate
- Lanark, Shotts and Whitburn
The areas proposed to move into Lanark, Shotts and Whitburn are Whitburn (obviously), East Whitburn, Greenrigg, Longridge, Fauldhouse. The new boundary of Livingston being just beyond Bents and Breich to the West. The southern boundary of the Linlithgow seat will the the Armadale and Blackridge/Whitburn and Blackburn ward boundary and the Western fringe will be at junction 4 of the M8.
Uphall, Broxburn, Dechmont and Ecclesmachen will move from Livingston into the new Linlithgow and Bathgate seat.
It will will mean that it will be possible for people in the Whitburn and Blackburn ward to have MSPs in common with either Lanark and Shotts, or Livingston and their MP in Common with either Linlithgow and Bathgate or Livingston. However, with the expansion in various areas this is the most equitable shape of the three leaving the elctorates based on 2007 as:
- Livingston 54,840
- Linlithgow and Bathgate 54,230
- Lanark, Shotts and Whitburn 54,930
