(paraphrasing the piffle)
Monday:  I’m a committed unionist and the DUP are the staunchest of all unionists.  If they continue to oppose the deal, I shall be obliged to stand with them and do the same.
Wednesday: The DUP are staunch unionists, and I shall listen very carefully to what they have to say before deciding how to vote, but if they abstain, that will be enough for me to be able to support the deal.

Friday:  Who gives a %# What the DUP think, anyway?
