In June 1990, Hamilton was recruited by the right-wing Monday Club activist Derek Laud to work for Strategy Network International, a firm specifically created to lobby against anti-apartheid movements and economic sanctions and for apartheid South Africa's 'transitional government' of Namibia set up in defiance of UN Resolution 435 on Namibian independence. Derek Laud was an ex-Monday Club activist and protégé of Hamilton's friend Michael Brown, who offered Hamilton a fee of £8,000 per year. Hamilton failed to register the paid-for consultancy. Hamilton took free trips to South Africa in the company of Brown.- David Leigh & Ed Vulliamy, "Sleaze, the Corruption of Parliament", page 136, - Select Committee on Standards and Privileges First Report iv.
