Look at how Northern Ireland’s numbers were changed
Reduce the number of Scottish MPs
I love the wonderfully simple solution to the Scottish MPs question by JohnO on the previous thread:-
“We have been here before. Until 1972 the former Northern Ireland Parliament at Stormont enjoyed full devo max powers. What was the messy, rough and ready, probably anomalous but characteristically ‘British’ answer to compensate the rest of the country? Simple. Just make the NI constituencies at Westminster far larger than their counterparts on the mainland.
Forget about the monstrosities of an English Parliament or the ghastly complexities of EV4ELs, simply reduce the number of Scottish MPs….
And, that’s it. Problem solved.”
For prior to the the 1920 Government of Ireland Act 105 MPs were elected for the whole of Ireland, of whom 30 represented constituencies in the six counties which we know as Northern Ireland. Along with the creation in the new state in the south an elected parliament for the six counties remaining in the UK was set up. This move was accompanied with a reduction of Northern Ireland seats at Westminster to just 12.
That continued to govern until, when, because of “the troubles” direct rule was introduced in the early 1970s. This meant that Northern Ireland was under-represented at Westminster. That was changed in 1982 when the total was increased to 17.
Simple. There is a precedent.
