Scots and Welsh like to spend money they don’t have?
While welfare dependence is a bigger problem in Scotland and Wales than it is in the UK, the Tories are associated with the (English) Aristocracy and Unionism in general. The only two parties that matter in Scotland are Labour and the SNP (Lib Dems haven’t apparently made as many inroads as they had hoped). Ditto the Welshies with Labour and Plan Cymru.
