Blair and Brown not invited to the Royal Wedding.

I don't suppose we will ever be told which spiteful person decided not to invite Blair and Brown to the Royal Wedding. I cannot believe that the Queen, sensible and above parties as she has shown herself throughout her reign, would herself have vetoed two of her former prime ministers, even if they should, in some way, have incurred her displeasure; but, if she did not personally make that decision, it does surprise me that she should not have overruled whoever was responsible for the exclusion.
