What does the 'West Lothian Question' pertain to?

The 'West Lothian Question' specifically addresses the issue of whether Scottish Members of Parliament (MPs) should have the right to vote on matters that are exclusive to England, particularly after devolution granted Scotland its own parliament with significant powers. This question arose from the situation where Scottish MPs could influence legislation affecting only England, while English MPs had no say in decisions concerning devolved matters in Scotland. The implications of this question highlight concerns about fairness in the legislative process and the balance of power between the different parts of the UK. Thus, the correct answer reflects a critical aspect of parliamentary representation and the complexities of the devolution settlement in the UK.
