this came to a head due to the leading role he played together with andrew feinstein (an anc mp) in launching an investigation into the multi-billion "arms deal". after feinstein was forced out of parliament by the anc he soldiered on for another year in order to try and keep pressure on the formal investigation to resist pressure that was put on it by the executive to whitewash the arms deal processes. the investigation however became severely politically compromised and as such avoided making any controversial findings - notwithstanding the substantial circumstantial evidence which existed to the contrary. his tough-on-corruption and tough-on-incompetence style of chairmanship caused considerable embarrassment to the ruling party which in turn led to his becoming so undermined that the committee itself became dysfunctional. he resigned his position as chairperson in protest of the politicisation of the committee and the weakening of its critical oversight role.
