People saying the coalition wasn't voted for don't understand how the British electoral system works. You vote for your local candidate. If they are part of a political party and not an independent, you're also voting for their party to be in government.
The party that wins the most seats gets the first chance to form a government. If they don't have a majority alone, they can form a coalition with another party. They are unlikely to choose the second largest party because:
- They wouldn't want a coalition partner with that much power - fewer seats is better (but they would still want a workable majority).
- That would leave the country with no real opposition, which would be hugely unpopular with the public.
- The two largest parties are unlikely to have overlapping goals and policies. Better to find a coalition partner with similar policies (this is why the Tory/Lib Dem coalition was so weird).
If you vote for someone in a political party, you are also voting for the leader of that party to form a coalition should that scenario arise.
The Tories have done the logical thing at first glance. The DUP are right wing and have policies that are closer to the Tories than, say, the Lib Dems. They have a suitable number of seats. They generally vote with the Tories anyway.
It is horrific for NI, it violates the GFA. These are valid reasons to oppose the coalition. I'm in NI and I am Not Happy.
But please don't say no one voted for it. Everyone who voted Tory or DUP did, whether they had considered the possibility or not. That's how the system works.
