A leading human rights campaigner in Bhutan, Teknath Rizal - freed last month by King Jigme Singye Wangchuk after serving ten years of a life sentence for subversion - says he may campaign for constitutional change unless the king grants him an audience.

Mr Rizal, a former royal adviser, wants to discuss the return from Nepal and India of more than one-hundred-thousand refugees from Bhutan who say they were forced to leave because they're ethnically Nepali.

The human rights organisation Amnesty International classified Mr Rizal as a political prisoner because of his calls for democracy and human rights.

Mr Rizal said he was hopeful that the King would be sympathetic to his demands. He's living in a hotel in the Bhutanese capital, Thimpu, and says the government has confiscated his house and property.
