Tsvangirai, who died on Wednesday, aged 65, battled Mugabe's regime and survived four assassination attempts
Tsvangirai's death ended a long campaign to lead his country. It was a campaign that brought him assassination attempts, beatings and accusations of treason.
The end came in a Johannesburg hospital, said Elias Mudzuri, a vice president of the Movement for Democratic Change party.
The opposition leader had been battling colon cancer for two years.
Tsvangirai was for many years Robert Mugabe's most potent challenger and even became prime minister in an uncomfortable coalition government for a few years.
His death leaves the opposition in disarray just months before national elections.
