Obama in Kenya: Corruption 'biggest impediment to growth'

The US president has urged Kenya to hold "visible" trials to tackle corruption, which he said could be the "biggest impediment" to further growth.

At a news conference with the Kenyan president, Uhuru Kenyatta, he said Kenyans must say no to corruption "at every level". He said Kenyans did not need to be "a forensic accountant" to see when corruption was going on.
