I am sorry to have to send a disappointing response, and I have informed His Royal Highness of your kind invitation. As you. are aware, this in no way re?ects on the subject matter and The Duke of Rothesay has asked me to send his very best wishes for the success of the conference but, sadly, pressures on the diary mean that it is simply impossible for him to be there. May I ask, however, if a message from His Royal Highness would be of any help? If so, I will put the necessary arrangements in . In the meantime, this comes with The Duke of Rothesay?s renewed thanks and kindest good wishes, - 5' 7; Mark Leishman The First Ministet' of Scotland
