RAMALLAH, West Bank (Reuters) - The Palestinian President suspended his chief of staff on Sunday, the official news agency said, after allegations by an ex-security officer that he tried to exploit his influence for sexual favours. The WAFA agency said President Mahmoud Abbas had ordered an investigation into the case of Rafik al-Husseini. Last week, Israels Channel 10 broadcast a report based on hidden-camera footage and interviews with a ex-Palestinian intelligence officer who alleged that Husseini had offered a woman employment in exchange for sex. Fahmy Shabaneh, the former intelligence officer, told Channel 10 he wanted to expose the case but complained nothing had been done as a result. The footage was shot some two years ago. Husseini was not available for comment on Sunday. He was due to go on television last week to discuss the issue but instead issued a written statement read by the broadcaster in which he said he had been the victim of a conspiracy. Abbas ordered the inquiry to report back in three weeks. In the footage, Husseini is asked by the woman for his opinion on Abbas. He doesnt like the people and the people dont like him, replied Husseini. Shabaneh also said he had evidence of financial corruption by senior officials in the Palestinian Authority, which receives hundreds of millions of dollars of Western donor funding each year. Tayyeb Abdel-Rahim, a senior Abbas aide, has described Shabaneh as a junior officer who was sacked more than two years ago for dealing with Israel and for committing a number of violations that breached integrity and honour. The report has done nothing to help the image of Abbas and the Palestinian Authority he runs from his West Bank headquarters in Ramallah. Perceptions of official corruption were one of the main reasons behind the defeat of Abbass Fatah faction by the Hamas group in 2006 legislative elections.
