Then there are the regional parties. Scotland, Wales, and Northern Ireland each has a regional assembly, though the one in NI is currently suspended. MPs sitting in the assemblies also have seats in the UK Parliament.*
Wales has Plaid Cymru (pron. Plied Come-ree), which is a moderate Welsh nationalist party, which is prepared to work in the UK parliamentary system, but favours Welsh independence.
Scotland has the Scottish National Party (SNP), with similar, if slightly more hardline and left-wing, goals to Plaid Cymru.
Northern Ireland… blimey, it’s complex. This is all off the top of my head, and I don’t live there, just take an interest in the news, so no doubt I’ll be corrected along the way…
While some parties do fall under left/right banners, most voting is decided by community loyalty.
On the Unionist/Loyalist side (wants to remain part of the UK) the main players are:
UUP (Ulster Unionist Party) - “moderate” vaguely conservative, supports the Good Friday Agreement (GFA), vaguely prepared to work with Sinn Féin, though has to bluster in order not to alienate its core electorate - which it did recently, losing out to the more hardline:
DUP (Democratic Unionist Party) - Run by firebrand lunatic Ian Paisley. Hardline Unionist, despises the GFA, refuses to negotiate with anyone (“No!”), though now is the majority party in NI and for the first time yesterday, Paisley visited Dublin, so probably softening its stance a bit.
PUP (Progressive Unionist Party) - affiliated with the Ulster Volunteer Force (UVF) terrorist group (now on ceasefire), but now claims to be committed to democracy. Supports the GFA.
On the Nationalist/Republican side (wants to join the Republic of Ireland) the main players are:
SDLP (Social Democratic and Labour Party) - committed to democratic means, desires a united Ireland, but is prepared to compromise.
Sinn Féin - affiliated with the IRA (now on ceasefire), hardline Republicans with Marxist roots. Now claims to be committed to democracy, supports the GFA, prepared to work with opposing sides in Stormont Assembly. Refuses to utilize seats in UK Parliament due to loyalty oath to the Queen. Now the majority party on the Nationalist side.
Attempting to span the divide:
The Alliance Party - I’m not really very informed of their opinions. They aim for integration and have members from both sides of the community. Not very popular.
And some other socialist, religious, fascist and communist nutjobs.
