It's the fourth and final summer special politics in a pub podcast and it rained, rather summing up the weather and the politics of this dismal summer. But this week's offering presented by James Millar is brightened by the return of Stuart 'sausage boy' Donaldson, the nation's youngest ex-MP. At 23 he was the member of parliament for West Aberdeenshire and Kincardineshire. By 25 he wasn't. He talks about the experience of being catapulted in and out of parliament and his views on Nicola Sturgeon, Alex Salmond and Keanu Reeves. Plus Jon Walker is along again to discuss Disneyland and Big Ben. All the big issues of the last week then.
