By Samia Nakhoul TEHRAN (Reuters) – President Hassan Rouhani won a resounding vote of confidence and reformist allies won 29 out of Tehran's 30 parliamentary seats in elections that could speed Iran's post-sanctions opening to the world, early results released on Saturday showed. Tens of millions thronged polling stations on Friday for a twin vote for the 290-seat parliament and the 88-member Assembly of Experts, which selects the country's highest authority, the supreme leader. President Rouhani's reformist allies made gains in the races for parliament and the assembly, both in the hands of anti-Western hardliners for years.
