It isn't about extra politicians. It is about equality and rights. How can it be equal and just for somebody from Inverness voting on legislation that does not impact on their own constituents as they have the devolved responsibility and accountability but does impact on every person in England but somebody elected in say Penzance to represent Cornwall can't vote on the same issue that affects residents of Inverness? It has been wrong since devolution came in. It does not make second class MPs. It makes each MP in the Union equal. The devolution of further powers to Holyrood has further highlighted the injustice and inequality of the West Lothian issue and it has been fudged for years. Labour will want to keep the status quo as they would need the 41 labour MPs to help pass legislation on the English.
Yep, spot on, this plus many other issues.
