The Kenya Medical Research Institute (KEMRI)-Wellcome Trust Research Programme is facing discrimination charges brought by six former employees. The group, dubbed the KEMRI six, are accusing the programme of exploiting African employees, impeding their career development, and giving preferential treatment and pay to researchers from developed countries. They also allege their work was stolen and given to researchers from developed countries. Many consider the KEMRI-Wellcome Trust Research Programme to be a model North-South partnership, praising its substantial support of African researchers. But others criticise what they perceive to be a failure to promote African scientists, or to involve them in setting research agendas. According to scientists in Africa and Europe, partnerships between rich and poor nations often generate tensions.
