Tsvangirai says no need to probe wife's death

"Around this time last year it was totally inconceivable that I will sit in the same cabinet with Mugabe.

"But now I will be the first one to defend his right to a place in the transition. Our relationship is business like."

Last year, Mr Tsvangirai who beat President Mugabe in March elections pulled out of the June 27 presidential election runoff citing mounting violence against his supporters.
