BAGHDAD (AP) – Iraq’s parliament on Tuesday unanimously approved an ambitious reform plan that would cut spending and eliminate senior posts, including the three largely symbolic vice presidencies, following mass protests against corruption and poor services.

Lawmakers approved the plan without debate, in a dramatic departure from the heated arguments and delays that have slowed previous efforts to approve important laws. Iraq’s most revered Shiite cleric, Grand Ayatollah Ali al-Sistani, had backed the plan, which was announced Sunday amid mounting public pressure.

Prime Minister Haider al-Abadi congratulated Iraqis in a message on his Facebook page, promising “to continue in the path of the reform even if it costs me my life with the trust in God and the people’s support.”

Parliament Speaker Salim al-Jabouri said he hoped that “today’s move will be the first and not the last to continue in the path of reform with the same spirit and without any hesitation.”
