For all the wrong reasons, it was a party to remember. The venue was London's Grosvenor House hotel, the host billionaire industrialist Subrata Roy and the guestlist a who's who of people who are Cherie Blair, Lord Paul and John Bercow. They were there because Royal Mail had issued a special set of stamps in recognition of Roy's work.
What the invitation didn't say – and what the host and guests apparently didn't know – is that these were privately commissioned "vanity stamps", which Royal Mail will print for anyone at a cost of £15.
