Kenya’s Public Prosecutor Noordin Haji says the state has recovered stolen assets worth $20m (£15.3m) from corruption cases.However, that is only 1% of an estimated $2bn (£1.53bn) worth of public money involved in high profile corruption cases.In recent years high profile politicians and public servants have been arrested and prosecuted for corruption, but none has been convicted yet.Mr Haji spoke to the BBC’s Ferdinand Omondi in Nairobi about his hopes of securing a high-status conviction this year - a challenge put to them publicly by President Uhuru Kenyatta on Monday.
