Views on Sinn Fein, Plaid and the SNP across the UK

[celticnations]

Curious what fellow Irish living in Northern Ireland, Wales or Scotland think about Sinn Fein, Plaid & the SNP?

I'm now living in Scotland & will be voting SNP. If I still lived in NI I'd vote Alliance.

In both countries I'd vote to leave the Union.

Internet searches show that the UK is abnormally hyper-centralised in favour of London & SE England.

Think ancient Rome, Troy, Carthage or Sparta. The UK acts like a city state.

Time to update the governance of the UK? If not by unification & independence then by "maximum devolution"? Or reforming FPTP?

Is it fair in the 21st Century that the voting intentions of one nation's voters dictates what happens to the Celtic/Gaelic nations?
