Amnesty has faced a troubled year

Kumi Naidoo has resigned from Amnesty International due to health reasons just 17 months into the role.

Naidoo said a medical condition worsened in recent months, and took the decision to following medical advice.

Julie Verhaar, Amnesty’s deputy secretary general yesterday will take on his responsibilities.

Naidoo said: “I have long considered Amnesty International as one of humanity's most important global assets, and it is with a heavy heart that I have taken the decision to step down from my position.

“Now more than ever, the organisation needs a secretary general who is fighting fit and can see through its mandate with vitality that this role, this institution, and the mission of universal human rights deserve.”

He intends to follow a phased transition by stepping down in January, when he starts a period of medical leave.

He said: “It has been a huge privilege to have worked with our excellent and committed staff and volunteers at the international secretariat as well as with our sections.

“I have been inspired by the important and courageous work being done by our movement. But due to my health, I have no choice but to take this painful decision and step down.

“I need to recover my health and figure out a more sustainable way to continue to contribute to the struggle for justice in the future.”

Naidoo’s resignation comes after a turbulent time for the organisation. Earlier this year a report found Amnesty had a “toxic” working environment with widespread bullying, public humiliation, discrimination and other abuses of power.
