This is a stunning picture of Edinburgh Castle but can you spot the deliberate mistake? Yes, there is something not quite right about the flag. That's why I was delighted to sign the e-petition to the Scottish Parliament demanding that the Saltire fly above the most imposing landmark in our capital city. The puzzling thing is why it has gone on so long. For more about the saltire see my previous Sunday Times column on Gerard Burns's Christmas card here.
If you like the photograph, apart from the flag, you can see more of the photographer's work on the flickr photo-sharing site
