Hundreds of Iraqi people took to Baghdad's Tahrir Square on Sunday to support recent decisions taken by Prime Minister Haider al Abadi.
The participants shouted anti-corruption slogans and waved Iraqi flags during their rally.
Abadi unveiled sweeping reforms to reduce government costs and fight corruption after protests across the country.
He said senior political appointments should not be based on sectarian or party quotas and moved to abolish the posts of vice-president and deputy PM.
Most of Abadi's proposed reforms will require parliamentary approval.
The move follows recent anti-government protests sparked by unreliable electricity amid a major heatwave.
