Kenyan President Mwai Kibaki on Thursday suspended an assistant minister who was among three parliamentarians detained on hate speech charges. Kibaki 'suspended Hon. Dr. Wilfred Machage from the office of assistant minister pending determination of the hate speech case in court,' said a stamement from the president's office. Machage, Kenya's assistant roads minister, as well as two other members of parliament, were arrested on Tuesday over alleged hate speech and incitement to violence during the campaign for an August 4 constitutional referendum. The assistant minister is accused of making several inflammatory remarks on the sensitive issue of tribes and land, warning several tribes they could be forcibly evicted from his constituency. The new constitution is one of the reforms that donors have been pressuring Kenya to push through since the end of the 2007-2008 post-election violence that left some 1,500 people dead. On Sunday, two explosions left six people dead at a rally against the new constitution organised by evangelical protestant churches in Nairobi. While the country's president and prime minister publicly back the new constitution, the reform is meeting some resistance from Kenya's rich and powerful over the crucial issue of land ownership. With Kenya's fractious political elite already jockeying for position ahead of 2012 elections, a clause of the constitution which some churches charge would effectively legalise abortion has also caused heated debates. The blasts at a weekend rally against the proposed constitution killed six people and wounded dozens, heightening fears of a return of the kind of violence that tore the country apart following disputed 2007 polls.
