UPDATE 1-MTN picks Harvard-trained executive to head Nigeria
* Michael Ikpoki to head Nigeria
* Serame Taukobong to lead Ghana (Adds details)
JOHANNESBURG, July 24 (Reuters) - Africa's largest mobile operator MTN Group on Wednesday named its Ghana chief executive to head up its key Nigerian business, in a job reshuffle sparked by the abrupt resignation of its chief financial officer.
Nigeria is the second-biggest revenue earner for Johannesburg-based MTN, which has operations in nearly two dozen countries in Africa and the Middle East.
Harvard-trained Michael Ikpoki is replacing Brett Goschen, who took over as CFO after Nazir Patel resigned this week following an investigation into allegations against him.
The company has said the allegations against Patel were over governance and would not impact its financial results. It has not given any other details.
Serame Taukobong, chief marketing officer for MTN's South Africa business, will take over as head of Ghana.
