There is joke about a successfull small business, to be successful start with a large company.
Take a look at these results from England in June 2016 (ignore the ni,wales (right) and bottom bit of scotland (top))
Would a conservative advocate devolution (my blog) ? in order to cling to power after all northern ireland,scotland and wales has it.
I believe i stated that I thought it could happen recently making Parliament a body with not much to do. It will be interesting to see if a conservative will dismember the union in order to rule..
It would make the tories into something the the snp in Scotland who still are the largest party. Northern Ireland votes according to religion. Wales as a region is an non entity if your Theresa May.
It is one way to call it a success.
