West Dunbartonshire crosses multiple Holyrood boundaries (approximate share of the seat's area in each): Dumbarton (76%), Clydebank and Milngavie (21%), Stirling (2%). Scotland uses the Additional Member System: voters cast one ballot for a constituency MSP and a second for a regional list. The figures below are the constituency vote.
| Holyrood constituency | Approx. share of West Dunbartonshire's area | Winner | Runner-up | Elected MSP |
|---|---|---|---|---|
| Dumbarton | 76% | Labour 39.8% | SNP 34.2% | Jackie Baillie |

Holyrood 2026 constituency results from official declarations. Overlap percentages are approximate shares of the Westminster seat's land area, not of its electorate. They come from an area overlay of the post-2024 Westminster boundary on simplified Holyrood second-review boundaries (in force from 7 May 2026), so they do not always sum to 100% and small overlaps may be artefacts of the simplified boundaries.
