Malawi President Bingu Wa Mutharika is demanding the resignation of the nation's chief prosecutor.

Mr. Wa Mutharika Thursday asked Public Prosecutions Director Ishmael Wadi to step down after he dropped all corruption charges against former president Bakili Muluzi.

Wadi has not responded publicly to the president's demand. The prosecutor said last week that he had no choice but to drop the corruption charges because Mr. Wa Mutharika had suspended the country's top anti-corruption official. He said Malawi's Anti-Corruption Bureau no longer had any officials senior enough to pursue the investigation.

No explanation has been given for the suspension of the anti-corruption official, Gustave Kaliwo.

Former President Muluzi was facing six charges of allegedly diverting large sums of government money into his personal bank account. He has denied the accusations.

The former president's arrest was part of a wide-ranging anti-corruption probe launched by President Wa Mutharika. The probe has led to the arrests of several former government officials.
