"refers to the DUP members who you continually refer to in such terms?"
Bit slow on the uptake Nigel - THE PAPERS have been full of it since Mayfly gave them a Billion of British taxpayers money
"by being elected by their Northern Irish constituents."
And this matters why exactly?
When Irish independence was finally won (sort of), Britain carefully divided Ireland into two parts ascertaining that the bit that remained as part of the Union was dominated by sectarian Loyalists loyal to Britain, even excuding three Ulster counties that would have tipped the balance the other way
This led to getting on for a century's inequality and repression which finally turned to open warefare when peaceful Civil Rights marches demanding equality were brutally beaten into submission with the help of British/Irish police (an echo of what had happened in the American South a decade earlier)
The North has been dominated by a fiercely sectarian anti-Catholic (up to now) majority set up be and loyal to the British Government - this is about to end as the two populations have almost reached parity   
So the "closer to home" you are referring to is still part of Britain - the Unionists describe themselves as British and have brought the country to the point of collapse on several occasions, first by introducing the gun into twentieth century Irish politics big-time, then by terrorising the third minority whenever it questions the six counties "Brutishness" - Northern Ireland's problem stems from its desire to call itself "British" Probably the greatest positive thing to come from the fiasco that is Brexit is that it has almost certainly guaranteed a United Ireland
All immaterial anyway - it was Thereas May who decided to spend a billion of the British taxpayers money to help her out of the massive hole she dug for herself by calling an election and losing a majority - she used British taxes as her own personal rainy-day piggy-bank
That the DUP was elected is beside the point anyway - whoever is elected becomes responsible for what happens to the country - the electorate no longer have a say in or bear any responsible for what happens - that is the sham of Parliamentary democracy

"There is no treachery, plain and simple."
Lads, lads, lads!!!
This pair of twots have brought up this so-called treachery to divert attention from the fact that Brexit has now become a long-running farce, a running sore - next step paedophilia, misogyny and antisemitism (probaly wife and mother nbrating thrown in for good measure)
If they were seriously concerned about Britain's security and well-being they would be up-in-arms about Ukip's links with LePen's fascists or British politics being interfered with by Russian bloggers or Mayfly spending Britain's hard-earned taxes on personal peccadilloes
on't feed the ****** trolls
