Nigeria’s former first lady has launched a tirade against the country’s president, Muhammadu Buhari, and his government’s efforts to claw back tens of millions of dollars that she allegedly siphoned off while her husband was in power.

Patience Jonathan, the wife of Buhari’s predecessor Goodluck Jonathan, railed against what she called an “unjustified witch-hunt” in a statement released in the name of her media aide, Belema Meshack-Hart.

The target for most of her anger was the country’s corruption watchdog, the Economic and Financial Crimes Commission and its acting chairman, Ibrahim Magu, whom she accused of being out to kill her and her husband.
