Oronto Douglas, the Special Adviser to President Goodluck Jonathan on Research, Documentation and Strategy, is dead. Mr. Douglas, 49, a presidency source said, passed on at the State House clinic at 4:58 a.m. Thursday. The real cause of his death is unknown at this time, but the presidential adviser is said to have managed a terminal illness for sometime, and had, from time to time, sought treatment abroad for prolonged periods. Born 1966, Mr. Douglas is regularly described as one of Mr. Jonathan’s most brilliant and influential aides, documenting the President’s achievements and legacies, and helping coordinate parallel media and campaign strategies for the presidency. “He was one of those who had the most far-reaching influence on President Jonathan,” a presidential aide said. A lawyer and committed environmentalist, Mr. Douglas was a commissioner for information in Bayelsa and was a delegate from the state for the 2005 National Political Reform Conference organised by the Olusegun Obasanjo administration. He emerged one of the shinning stars of that conference as the Niger Delta region pushed for improved revenue allocation to the area to mitigate the effect of oil exploitation.
