Max Pearson presents a collection of this week's Witness History episodes from the BBC World Service. Our guest is Dr Ongama Mtimka, lecturer in South African politics at the Nelson Mandela University. He tells us about Mandela's life and legacy 10 years on from his death.

We start with with Mandela's daughter, Makaziwe, describing her relationship with her father and planning his funeral. Then, the brother of Emanuela Orlandi describes his lifelong mission to unravel the mystery of her disappearance in Rome in 1983.

The second half of the programme has a Russian flavour. A relative of Tsar Nicholas II describes the murder of the Romanov royal family in 1918. Then a Russian journalist describes attending the Romanov's controversial reburial 80 years later. We finish with one of Russia's greatest poets, Anna Akhmatova.
