Headline in the Guardian:
David Cameron: I will not resign if Scotland votes for independence
It reminds me of the Monty Python sketch about hapless gangsters, the Piranha brothers:
they began to operate what they called ‘The Operation’. They would select a victim and then threaten to beat him up if he paid the so-called protection money. Four months later they started another operation which the called ‘The Other Operation’. In this racket they selected another victim and threatened not to beat him up if he didn’t pay them. One month later they hit upon ‘The Other Other Operation’. In this the victim was threatened that if he didn’t pay them, they would beat him up. This for the Piranha brothers was the turning point.
If Cameron really wants to preserve the union, he needs to switch to the other other operation, promising that he will resign if Scotland votes to stay in the UK.
