CAIRO - The two sons of Egypt's former president were back in court on Monday facing charges of stock market manipulation, five weeks after separate corruption charges against them were thrown out.

Gamal and Alaa Mubarak, with seven other men, were charged with violating stock market and central bank rules to make unlawful profits through dealing of shares in Al Watany Bank of Egypt.

Mubarak's eldest son, Alaa, is a businessman. His brother Gamal, a former banker, was widely viewed as being groomed for Egypt's top job until Mubarak was toppled in February 2011.

Wearing white prison uniforms, they sat in a steel cage reserved for defendants in the court at a Cairo police academy as a prosecution official read out details of the charges. The other executives wore suits.

"This has absolutely no basis in fact. I deny these charges in whole and in their details," Gamal Mubarak told the judge. His brother said: "Unfortunately, sir, this is all lies and defamation."
