We've had the McMuffin, the McNugget and the McFlurry. If Basil McCrea and John McAllister do form a new party might they consider calling it the McUnionist Party? Think of the slogan, 'We're lovin' it!'
Or maybe they'll drop the unionist label altogether, choosing to emphasise something other than the national allegiance side of their beliefs and go for a simpler moniker – The Big Macs.
If David McClarty joins they could be The Three Mackseteers. And if they could persuade Jo Ann Dobson to defect to their ranks that'd make them Three Men and a Babe. (ish)
They'll have to do well from the start. They don't want to end up being known as the Three Men in a Boat (Up S*** Creek Without A Paddle)
Whatever happens, they should have a party to celebrate being together, celebrate their alliance. Oh, wait a minute. An alliance party? Now there's a good idea...
