Apropos your recent article on signposting prices and brands of petrol on the motorway, did you know there is actually a law against declaring what is being sold at petrol stations? This old law goes back some considerable time, but it is typical of something that the Government cannot be bothered to do anything about. I have already complained about it to Oliver Letwin my MP. I do agree with you that in France it is very useful to know what type of fuel is available, where and at what price.
