Former Kenyan Prime Minister Raila Odinga has died at the age of 80, a source in his office told Reuters on Wednesday.

He was said to have suffered a cardiac arrest while on a walk in India.

Odinga, who had been receiving treatment in the southern Indian city of Kochi, suffered a cardiac arrest on Wednesday and was rushed to hospital, where he was pronounced dead.

He was the leader of the Orange Democratic Movement in Kenya.

A veteran opposition leader, Odinga ran unsuccessfully for Kenya’s presidency five times. Two of those elections — in 2007 and 2017 — ended in chaos, sparking violence and deep divisions in the country.
