President Viktor Yushchenko fired Ukraine’s Prosecutor General Svyatoslav Piskun on Saturday. Concorde Capital: Piskun has been under fire for failure to make any progress in several high profile cases, including the murder of journalist Georgiy Gongadze. However, the firing has raised some eyebrows as it comes only a week after Piskun opened abuse of office charges against former National Security and Defence Council Secretary, Petro Poroshenko.
