I happened across a link to this site ( http://www.thankyoutony.com/) just now. It has an online form to allow users to enter their thankyou message to Tony, to be printed and sent to him.

You can enter whatever message you like, so you can thank him for anything you like ;)

Thank you for taking Britain into an illegal war
Thank you for making it easier for terrorist organisations to recruit new members
Thank you for allowing cluster bombs and DU to be used in Iraq
Thank you for hiding the unpleasant truth from Britons
