Well this is a surprise. Very good move on his part; helps to raise the problems of this award and the gruesome history of the Empire.
Not too sure what an MBE entails, I don;t think they get any cash for it. Seems like they just get an empty title and a little visit to the palace. I think the irony here is, that title of MBE will probably get him more kudos abroad in former "colonies".
Colonialism is of the mind nowadays, well done on Howard for making a stand.
