The first episode of George Osborne and Ed Balls’s new podcast, Political Currency, opened with an old clip of the pair arguing across the despatch box. Osborne had described his latest Budget as ‘steady as she goes’ and Balls was having none of it. ‘What kind of ship does he think he’s on, the Titanic?’

If producers hoped that the duo would bring something of this, er, biting dynamic to their podcast, they were in for a surprise.
