Iran hardliners won't derail nuclear deal: official Iranian MPs won't derail a nuclear deal with the West, as US lawmakers have threatened to, if the country's supreme leader gives it his backing, parliament's top official said Monday. Speaker Ali Larijani said lawmakers and the government would be unified if an agreement gets the nod from Ayatollah Ali Khamenei, who has the final word on all policy matters in the Islamic republic. Larijani's intervention appeared to neuter repeated demands from hardline conservative MPs that an agreement with world powers can only be binding if it is ratified by parliament.
