He said to BBC News that gay rights were a "human right" that should be respected by Zimbabweans.
"It’s a very controversial subject in my part of the world. My attitude is that I hope the constitution will come out with freedom of sexual orientation, for as long as it does not interfere with anybody," he told Newsnight’s Gavin Esler, adding "To me, it’s a human right."

Of course, words are not acts. In Zimbabwe, it is always illegal that two same sex people hold hands, hug or kiss.
