Kenya's president has suspended four cabinet secretaries and 17 other senior officials to facilitate investigations into allegations of corruption.

A statement read by President Uhuru Kenyatta's spokesman Manoah Esipisu said Saturday the officers have been named in a confidential report by the Ethics and Anti-Corruption Commission.

The suspensions have been met with skepticism by members of the public as senior officials suspended in previous regimes have never been convicted and some returned to their Cabinet positions even before investigations were complete.

Anti-corruption activist Boniface Mwangi said high-ranking officials are rarely convicted in Kenya, instead they make their way back to power.

Transparency International, in its 2014 corruption perception index, ranked Kenya close to the bottom — 145 out of 175 countries.
