The UK along the lines of other countries could go through a period of formal or loose coalitions, so I find the barrage of hostility to the DUP democratically worrying - especially as ‘the will of the people’ has just decided that whether a Tory or Labour administration, BOTH needed the DUP’s 10 votes to effectively govern.
To my knowledge in those other countries with coalitions there is ALWAYS A PRICE for the smaller party support.
In 2015 I remember the SNP Salmond saying on the BBC that the SNP under him would demand “billions” more direct spending for Scotland and a £180 billion of more Westminster borrowing, but how and where that was to be spent I don’t think was mentioned, but he did say something along the lines of he would rewrite Labour’s first budget under Ed Balls.
During the recent election although Labour’s official position in Scotland was ‘unionist’, yet Corbyn did say a week before the election that he would open discussions with the SNP about another independence referendum after the general election, while Sturgeon’s SNP manifesto promised to ‘free up’ £118 billion of public investment for Scotland, with no detail I saw.
So it would seem any Westminster coalition requiring support from ‘nationalist’ MPs representing Northern Ireland, Scotland and (no doubt) Wales, will come at a price.
And based on the fact the SNP and Plaid Cymru say they will only ever support a Labour government, and the DUP would be unlikely to support the current Labour leadership unless see a cash offer they could not refuse – I would suggest £1 billion spent of NI public services will turn out relatively cheap, at a time Brexit negotiations has just started the DUP agrees on, while the SNP does not.
