Former struggle icon and fraudster Allan Boesak on Tuesday became the latest high-profile figure to join the newly-formed Congress of the People.
He announced his decision at the final session of Cope's three-day founding conference in Bloemfontein.
Boesak rose to prominence in the 1980s as a churchman and a leader of the anti-apartheid United Democratic Front.
He served a brief jail sentence in 2000 after being convicted of fraud and theft of over R1.5 million of donor funds.
A former head of the Geneva-based World Council of Reformed Churches, he has held senior positions in the NG Sendingkerk, and was a driving force behind its adoption of the prophetic Belhar Confession.
