SMALL Business Development Corporation managing director George Etrelezis will officially leave the organisation this week, ending the reign of one of Western Australia’s great political survivors. Mr Etrelezis is understood to have spent more than two decades at the head of the entity charged with assisting the development of small business in the state. A spokesperson for Small Business Minister Norm Marlborough said Mr Etrelezis was negotiating redundancy terms. He is understood to have taken leave and his former deputy Steve Moir is in the role of acting CEO.
