Royal Special

This month on Witness, Razia Iqbal introduces us to five people whose stories help illustrate the changing nature of royalty in the twentieth century. We'll meet the great niece of the last Tsar of Russia, the Bulgarian King exiled by communists who returned as Prime Minister, the woman whose sister's marriage to an African monarch caused a scandal and we'll hear about the Japanese royal wedding that broke two thousand years of tradition plus the story of how Princess Diana changed the world's attitude to AIDS with a photograph.
