I could have titled this "Just what is your problem?", but we know what it is. They cannot stomach sharing power with Sinn Fein and are going for delaying tactics.
But it's sad that they are arrogant to be the only ones who find this difficult. Many who want to see this power sharing happen (inc myself) have long memories, but it's important for Northern Ireland's future that this happens. The DUP have wedded themselves to power sharing, Gordon Brown has promised an extra £1bn if they go ahead tomorrow, so is there any good reason for delay?
And the sad thing is that they are not letting down Sinn Fein, or the British or Irish governments. It's the good people of Northern Ireland they are letting down!
