Breyten Breytenbach, the jailed South African writer, has won a literary prize awarded by the pro-government press, for a book of poems written in prison. Mr Breytenbach was sentenced in 1975 to nine years' imprisonment for alleged subversion on behalf of the banned African National Congress. The prize was awarded by the Perskor group which owns Die Transvaler and other Afrikaans newspapers. It is for a collection of poems entitled Voetskrif (Footnote). The prize money of 2,000 rand has been handed over to the poet's brother.
