Martin Geissler sits down with Scottish Liberal Democrats leader Alex Cole-Hamilton. The Liberal Democrats election campaign is well underway, with Sir Ed Davey, the party's leader, whizzing down waterslides and falling into lakes. But will it win them votes? In this audio version of the BBC Scotland Sunday Show interview, Martin asks Cole-Hamilton about energy, housing, Brexit, independence, and more.
