Egypt's Opposition Leader Ayman Nour has been sentenced to five years in jail for forgery by a Cairo Criminal Court. The 41-year-old went on trial six months ago on charges of forging affidavits for the creation of his Ghad Party last year. Nour and his wife shouted "Down with President Hosni Mubarak" when the judge read the sentence. Among Nur's six co-defendants, two were sentenced to five years in prison, three to three years and another was sentenced to 10 years in absentia. Nur, who was President Mubarak's main challenger in the September presidential election, has always denied the charges. He says they were trumped up by the regime to undermine his political career.
