I did not know that -- any idea why the change?
and thank you for correcting the latter statement of mine
Well, not all Conservative.
Whilst much of rural Scotland and some towns and cities were Tory, there have always been working class areas, esp around Glasgow, that have been socialist. Glasgow was famous in the 20’s/30’s as ‘Red Clydeside’. It was a Scotsman from Ayrshire who founded the Labour Party after all. Albeit the older socialism was a more responsible socialism and not the entitlement mindset of today.
As to why, simply the cultural/political change, as society became more liberal through the 50’s and into the 60’s.
