RAMALLAH, May 5 (Reuters) - The millionaire businessman son of Palestinian President Mahmoud Abbas is expected to run for a steering role in his 90-year-old father's political party, sources say, as a succession fight looms for control of the embattled Palestinian Authority. Yasser Abbas runs tobacco and contracting firms in the parts of the Israeli-occupied West Bank where the PA exercises limited self rule. His critics have long accused him and his brother Tarek, also a businessman, of using public funds to fuel their businesses, allegations both men reject.
