Chris Grayling is an advertising asset for a future Scottish No vote

The SNP’s core message at the general election was that more nationalist MPs would mean a “strong voice” for Scotland at Westminster. Chris Grayling’s planned demotion of all 56 nationalist MPs to second-class citizens in the mother of parliaments, coupled with this week’s overwhelming defeat in the Commons on any move toward full fiscal autonomy, suggests the word “strong” is massively overplaying the reality of Scotland’s influence at Westminster.
