George Alagiah is to present a new programme, NewsHour, on BBC World.
Beginning in June, the programme will broadcast each weekday during peak times around the world, including the US breakfast and Asia evening slots.
Alagiah will present NewsHour from Monday to Thursday, and will continue to co-present the BBC’s Six O’Clock News.
BBC global news director Richard Sambrook said: "George has achieved tremendous success for his objective coverage, in-depth international knowledge and sharp interviewing skills. His experience and ability to uncover the news behind each story will be crucial for the success of NewsHour."
Alagiah joined the BBC in 1989 and worked as a foreign correspondent, specialising in Africa and the developing world. In March 2002, he launched BBC Four’s international news programme and began presenting BBC’s Six O’Clock News in January 2003.
His reports have included the famine in Somalia, the genocide in Rwanda, Saddam Hussein’s campaign against the Iraqi Kurds and the aftermath of 9/11 attacks on New York.
