Barnett squeeze

Is reform of the way Scotland, Wales and Northern Ireland the burning political issue of the day?
Not if this one-line Commons motion calling for a review of the system is anything to go by. Just 10 MPs have signed it so far.
In many ways the Conservatives have most to gain, in electoral terms, from any public resentment in England about perceived higher spending levels in Scotland, so perhaps it's not surprising that none of the party's MPs have signed up so far. And maybe this explains the lack of SNP names.
