Tomorrow will mark Desmond Tutu's 77th birthday and he continues to crusade for justice both in South Africa and globally. Tutu is no stranger to controversy, but when all is said and done he has been a vital figure in his time, the central moral voice within South Africa during the last years of Apartheid and the public face of the Truth and Reconciliation Commission. He would have been lauded had he settled for peaceful retirement years ago, but instead he goes on strong. Let us hope he continues as a voice of conscience and goodwill for many years to come.
