Am I alone in getting irritated by the broadcasters' use of helicopters? The Prime Minister goes to Buckingham Palace to ask the Queen for a dissolution, and his motorcade through central London is covered live on TV via a helicopter. I suppose at least you could say that is a way of visualising a constitutional ritual. But then he sets off to St Pancras to get on a train, and we have to watch that journey from a helicopter as well. It is of no conceivable interest, except perhaps to notice in passing how many one-way streets the PM is allowed to go the wrong way down. It is wasteful of BBC licence-payers' money, exceedingly un-green in fuel terms, and damned noisy to boot, if you happen to be in the streets concerned.
