Agree with all of this. Never use words when images are available!

I too remember Lord Howe fondly. I had a long chat with him when he was visiting Moscow in the early 1990s. He said that the scariest moment in his political career ("my only sleepless night") had been the abolition of UK exchange controls in October 1979, when he was Chancellor of the Exchequer. Economic theory said that the impact should be beneficial; but no-one really knew for sure. In practice, the reform helped consolidate UK dominance in the financial services industry. I often use this story to illustrate the difficult truth that politicians have to "let go" of some things, albeit within a legislative framework, rather than trying to control everything - which leads inevitably to bad decisions. A lesson still for many politicians around the world.
