where the public sets the agenda It's my Life, Anyway ...
John Hadley wants to live a full life. Not only does he want friendship and family but also to do the simple things we all take for granted, like being able to wear his own clothes, spend his own money, or to go out when he wants. Now Maureen Ronksley can help him to do this. She is his advocate: a trained volunteer who represents the interests of a mentally-handicapped person living in hospital as if they were her own.
Open Space looks at this revolutionary scheme based on relationships of friendship and trust designed to transfer personal power to people like John Hadley and 50,000 others who have always been denied it.

Presented by John Tusa Sex and the Victorians
Did Victorian wives really 'lie back and think of England'? New research suggests they enjoyed a far more liberated sex life than conventional image allows.
God Save the King was first associated with George III. Why did the king who lost the American colonies become adored by his people, with the first royal souvenirs manufactured in his name? Stalin's Famine
Fifty years after millions of Ukrainian peasants died in Stalin's collectivisation, survivors remember the tragedy the Soviet Union still -ignores. Malcolm Muggeridge recalls reporting the suffering.

True Confessions of an Albino Terrorist
Breyten Breytenbach writes about being an Afrikaner. His poetry was taught in schools and his paintings greatly admired. But in 1975 Breytenbach, living in self-imposed exile in Paris with his Vietnamese wife Yolande - their marriage was regarded as 'fornication' under South African law - decided to return to his native country under a false passport, with the intention of recruiting workers against the Government and its policy of apartheid. Breytenbach was betrayed, arrested and sentenced to nine years. This year, two versions of his horrific experience of South African jails are to be published - Mouroir, a surreal account of his life in prison and True Confessions of an Albino Terrorist.
Tonight Arena presents the story of this extraordinary man including some of the poetry and paintings completed in prison and smuggled out of South Africa.
