Resolves “yes” if Wales has left, or is clearly in the process of leaving, the UK by 2040.

Resolves “no” if Wales is still in the UK on 1st January 2040 and isn’t in the process of leaving.

If there is a referendum on independence which ends after Jan 1st 2040 then the deadline will be extended until after that referendum finishes.

Resolves “n/a” if either the UK or Wales ceases to exist (e.g. by being annexed by another country) but not if they simply change their name but otherwise remain functionally the same.
