Tunisia swore in Moncef Marzouki as president on Tuesday, its first president since the regime of former President Zine el Abidine ben Ali was toppled during the Arab Spring earlier this year . . . Marzouki, a human rights advocate and leader of the center-left Congress for the Republic (CPR) party, was elected on Monday by the assembly after receiving 153 out of 217 votes . . . 44 opposition leaders turned in blank ballots due to concerns over power being concentrated in the hands of the prime minister . . . Marzouki’s next task will be to appoint his prime minister, who is expected to be Hamadi Jebali, from the moderate Islamist Ennahda party . . . Jebali will have 21 days to form a government . . . Marzouki faces a heavily skeptical populace that mistrusts the government . . .  Marzouki's coalition of the CPR, the Islamist Ennahda party, and the centrist Ettakatol party (FDTL) could suffer if it is unable to form a functional government . . . Marzoujki and Jebali will also have to placate secularists who are concerned that the majority Ennahda party will try to impose Sharia law on the country.
