Robert Ntambi  Mukasa was one of the  best friends  of Sir Edward Mutesa, the Ssekabaka of Buganda . He was the only person to escort Sir Edward MUteesa on the plane to London when Sir Edward had been exiled by the British to United Kingdom  in 1953.To proved this, at the time of the kabaka's exile to the Uk,  the Kabaka was asked by the Governor - Sir Andrew Cohen to choose one person he would like to go with to Uk in exile, and the Kabaka chose Robert Henry Ntambi Mukasa. The reason why the exilled Kabaka chose Robert Ntambi Mukasa to accompany him to his exile instead of the Nabagereka or his ministers is still a mystery. This shows the closeness of Robert Henry Ntambi to the late Sir.Edward Mutesa's life.
