Source Notes
The United Kingdom: Name, Union, Neighbours - Source Notes
An intermediate note for organizing research material, evidence links, issue structure, and inclusion decisions before the reader-facing article is written.
Scope
This note supports the report on the formal name of the United Kingdom, the distinction between Great Britain and the United Kingdom, relationships with neighbouring jurisdictions, and the 2026 situation of each constituent country.
Main Sources
- UK Parliament’s Act of Union 1707 page was used for the creation of Great Britain.
- Hansard’s 1927 Royal and Parliamentary Titles Bill debate was used for the shift to Great Britain and Northern Ireland.
- ONS mid-2024 population estimates were used for population growth and demographic components.
- Scottish Parliament Information Centre’s 2026 election briefing was used for Scotland.
- House of Commons Library’s 2026 Senedd election briefing was used for Wales.
- Northern Ireland Executive’s Programme for Government 2024-2027 was used for the current Northern Ireland policy framework.
- GOV.UK’s UK-EU Common Understanding and UK-Ireland Summit statement were used for neighbouring and post-Brexit relationships.
Inclusion Decisions
For the formal name, parliamentary and legal sources were preferred over encyclopaedic summaries. Because the legislation.gov.uk page for the 1927 Act was unstable in the browser view, the report relies on Hansard’s official parliamentary explanation and the legislation record for the Act’s title and purpose.
Limits
This report reflects sources checked on June 17, 2026. Party distribution, UK-EU negotiations, and Northern Ireland institutional practice can change quickly.
