On Thursday, the UK's Serious Fraud Office (SFO) halted a probe into the corruption case, saying Kenya was not cooperating with the investigation. Attorney-general Amos Wako blamed the delay on the country's judicial system. The SFO began its probe in July 2007 after receiving a request for the Kenya Anti-Corruption Commission (KACC), and was investigating offshore accounts in the British tax havens of Jersey and Guernsey. Three ministers, including the then Finance Minister David Mwiraria, resigned in 2006 to pave way for investigations, although two were later reinstated. Mwalimu Mati, the head of an anti-corruption watchdog, accused the government of conducting a cover-up of the scam. "The government has now declared that it truly is not interested in fighting corruption and indeed is engaging now on a daily basis in corruption scandals which ultimately may dwarf Anglo Leasing," he said. The SFO has conducted several investigations into international corruption cases, including allegations that a British arms company, BAE Systems, paid bribes to secure deals in Saudi Arabia and Tanzania.
