President Hosni Mubarak's younger son Gamal further stamped his authority on Egypt at the ruling party's conference yesterday, declaring his camp's victory over the old guard. In a keynote speech to members of the National Democratic Party (NDP), the 41-year-old Gamal Mubarak took much of the credit for his father's Sept. 7 election landslide and set the tone for the November parliamentary polls. "During the presidential election, the party proved its ability to modernize, proved the worth of the ideas it is has been promoting since the party took a new orientation in 2002," he said.
