sidewayspeak:-
"I have no desire to have Scottish/Irish/Welsh politicians dictating to England"
There are 650 MPs in the House of Commons. Of this total 18 are from Northern Ireland, 59 from Scotland and 40 from Wales. That means 533 of these MPs represent constituencies in England. Who's dictating to whom? This is especially pertinent at the moment considering not one Conservative MP was returned from a seat in Scotland.
Also I understand that the SNP actually bans it's MPs from voting on legislative matters which do not affect Scotland, thus negating their impact with respect to the West Lothian Question.
