I'm a bit lost on them aswell. I'm not great on N.Irish politics.
They sound kinda crazy to me from what I've heard this morning. Semi-climate change deniers, strict protestants, plus links to para-militaries and terrorist groups I think. Wonder if the Tory press will mention that
Certainly doesn't sound like an agreement, formal or non-formal, that can hold. That's before you even consider their position on the single market + common travel area etc.
