Politicians are duty bound to praise their national dishes: tough for Alex Salmond, who has to champion a diet of haggis and ‘neeps.’ And deep-fried Mars bars.

While discussing the Commonwealth Games this week, Alex gamely downed a glass of Irn-Bru - though as an illustration of his restraint, he pointed out that he’d gone sugar-free.

Perhaps he’s going easy on the sugar so he can munch one of those giant opening ceremony Tunnock’s tea cakes. Now that’s a foodstuff to be proud of.
