Here are a few options for a formal rewrite, depending on your preferred level of conciseness:
- Option 1 (Most formal/Direct): “Former Prime Minister Al-Sudani’s Coalition Issues Warning Regarding Misinformation on Corruption Probe”
- Option 2 (Journalistic/Concise): “Al-Sudani Coalition Cautions Against Misinformation Concerning Corruption Investigation”
Note: If you are referring to the current Prime Minister of Iraq, Mohammed Shia’ Al-Sudani, you may want to remove the word “Former,” as he is currently in office. If he is indeed a former leader in your context, the titles above are correct.
