Sometimes politicians write perfect political cartoons in the form of soundbites. I think this means communication which zings from one mind to another with the least possible interference. The Lib Dems shadow chancellor Vince Cable delivered one last night at Channel 4‘s Ask the Chancellors Debate when he was talking about the behaviour of some investment banks since receiving the UK taxpayer bailout. It reminded me of my drawing about over-powerful institutions facing the end-of-their-road. I’ve edited this piece to take account of Cable’s observation.
