At St Andrews the DUP insisted on an amendment to the 1998 Belfast Agreement that provided that the leader of the largest party at Stormont was to be the First Minister.
This was no gaffe. It was a deliberate ploy to be used in the very situation we now find ourselves.
And we are in danger of falling for it.
The prospect of a Sinn Fein First Minister would be tough for the Unionist electorate. The DUP have used this spectre in the past to blackmail the electorate into voting for them.
Now that their star is waning, and Unionism may be split three ways, they are using the same argument to try and do a deal with us so that they can hold on to something.
It is against this background that we should look at the private Hatfield House talks last weekend.
A week ago the Ulster Unionists were on a roll; the DUP in disarray over Robinsonsgate and a decisive by-election win with 64% of the vote in Lurgan, following on from a great result in the European poll earlier in the year.
Now there is angst amongst some in our party that if we fight an Assembly election and beat the DUP we will be a smaller party than Sinn Fein. The prospect of being deputy to Martin McGuinness is not palatable.
The DUP are in big trouble; they want to save their skins by destabilising our deal with the Conservatives. Shoring up their own supporters with talks of electoral pacts to save Robinson's skin is how they hope to survive intact.
But when have the DUP ever shown any concern for the common good; their tactics over the years have always been to predict doom and gloom if the electorate follows us, and then, when they achieve power to steal our clothes. They are at the same game today - remember how they wanted to do a deal with Cameron - but he wouldn't have them.
If, in an Assembly election, we were to end up the largest unionist party, with Sinn Fein as the largest party overall, what might happen? If we were unable to form an executive, another election would be triggered. The electorate’s minds might be concentrated by that; and a second Assembly election in short order would give unionist voters the chance to sort things out.
