Scotland, NI, Wales sign joint self-determination declaration

The first ministers of Scotland, Northern Ireland, and Wales signed a joint declaration asserting their nations' right to self-determination, a notable collective move that could signal coordinated pressure for constitutional change within the UK. The declaration's legal and political implications are unclear, and it may be largely symbolic, but it marks a rare unified front among devolved administrations. This could escalate tensions with the UK central government and influence future independence referendums.
