Kenya's government has missed its best chance to stamp out rampant corruption and faces a tough task to regain credibility, Transparency International (TI) said last Thursday, International Anti-Corruption Day. More than half of Kenyans do not think graft is decreasing, TI Kenya executive director Gladwell Otieno said. "The political class's dismal performance over the past two years has resulted in a highly negative perception by Kenyans," Otieno said at a news conference launching TI's Global Corruption Barometer survey.
