Compared with what's going on elsewhere in the world, London seems to be relatively peril-free at the moment. But I did hear that Tube workers are threatening a strike on the day of Prince William's wedding in April. Whilst I can't quite see myself up there standing in the crowd, waving a flag, I think it's a shame to want to spoil people's day. Never mind the message it gives to our tourists. Bad idea. Witless, in fact.
