A former speaker of Iran’s parliament registers to run in the Islamic Republic’s upcoming presidential election, becoming the first high-profile candidate to potentially back the policies of the outgoing administration that reached Tehran’s tattered nuclear deal with world powers. The decision by Ali Larijani, long a prominent conservative voice who later allied himself with Iran’s relatively moderate President Hassan Rouhani, comes on the last day of registration for the June 18 election. While a panel overseen by Supreme Leader Ayatollah Ali Khamenei ultimately will approve candidates, Larijani has maintained close ties to the cleric over his decades in government.
