Kenya's President Mwai Kibaki says he will take decisive action within days in the multi-million-dollar corruption scandals rocking his government.
His pledge Thursday came after Kenya's former anti-corruption chief told British television that he came under high-level pressure in 2004 to abandon a fraud investigation.
The BBC played excerpts of a tape John Githongo says he recorded when Kenya's then-Justice Minister Kiraitu Murungi pressed him to give up the probe.
Githongo, who left Kenya last year, has linked Murungi and other top Kenyan officials to a massive corruption scandal, known as the "Anglo-Leasing" affair that diverted more than $200 million from the government.
Murungi and the other officials deny any wrongdoing. However, Kenyan anti-corruption activists say they will post the names and pictures of the accused officials in public places to maintain pressure on Mr. Kibaki.
