The SNP says that if the UK moves toward a written constitution, it must include a clear method for leaving the union. Reporting from the Evening Standard and Belfast Telegraph focuses on the party’s position that constitutional arrangements should explicitly address how any part of the UK could withdraw from the union. The Evening Standard notes that the Prime Minister first raised the idea of a written constitution in 2024, setting the context for current debate. The reports agree on the SNP’s central argument: a written constitution should not only set out institutions and rights, but also include an agreed process for exit. They do not present details on the specific form of such a mechanism or when any constitutional legislation might be introduced. Overall, the coverage reflects an ongoing political discussion about constitutional change, with the SNP pressing for explicit provisions related to union withdrawal as part of any prospective written constitutional framework.
