The latest probe is focused on a military-orchestrated campaign forcing Prime Minister Necmettin Erbakan from office in 1997 over perceived threats to Turkey’s secular order, in an episode often referred to as Turkey’s “post-modern coup.”

Current Turkish President Abdulah Gul and Prime Minister Recep Tayyip Erdogan were top officials in the government at the time. They formed a new party in 2002 which won the elections.

An investigation has been launched against 50 former and active officers suspected of being involved in the coup.
