Before the recent Scottish independence referendum, promises squeezed out of the ‘Westminster establishment’ over more decentralisation of power to Scotland. The independence referendum was a close run thing. Now those in favour of full independence for Scotland are in a majority, and it seems that this will be reflected in the coming UK General Election.
The UK government has also conceded to a small increase in the powers of the Welsh Government.
On independence and devolution, Scotland has form, of course. But there are more modern reasons for the recent rise of pro-independence sentiment.
