The Movement for Democratic Change (MDC) family has lost a guiding light, with the death of Professor Gordon Chavhunduka, Prime Minister Morgan Tsvangirai has said.
Professor Chavhunduka, (81), died last week at the Avenues Clinic after battling cancer of the throat for the past two years.
A founder member of the MDC, Prof Chavhunduka was appointed Chairman of the Guardian Council last year, a body responsible for giving advice to the party.
Speaking at the funeral church service, at the Anglican cathedral, PM Tsvangirai, who is also MDC President, said Chavhunduka had made an indelible mark on the nation's history.
"He was a true giant of our time. We were highly favoured in the MDC when he joined the party hence the decision to appoint him chairperson of the Guardian Council. He had a wealth of wisdom. We have lost a guiding light in the party," the PM mourned.
The Premier described the late Professor as a person who fought to bring freedom and dignity to everyone including the down trodden.
"His many works speak for themselves and even as we write the new constitution the Copac draft has a clause that enforces recognition of traditional knowledge and this was made possible by him," he said.
"We are grateful to the Chavhunduka family for the unique gift that was with us. We have indeed been robbed of an important leader," he added.
Vice Chairperson of the Guardian Council, Sekai Holland, celebrated the life of Chavhunduka and said: "he lived a life of a true African man, ready to give advice to all those who interacted with". The MDC described Prof Chavhunduka as a true hero for real change.
"He was a leader, an advisor and a liberator," the party said in a statement.
Prof Chavhunduka, who leaves behind a wife Rachel and five children, will be buried at his farm in Dowa Rusape on Tuesday.
