Levan Mikeladze, a former diplomat turned into a politician from opposition Alliance for Georgia, died apparently from heart attack at the age of 52, the Georgian media sources reported.

Mikeladze was Georgia’s ambassador to Switzerland before stepped down in 2007 in protest against the break up of the November 7 protest rally. He joined Irakli Alasania’s political team in February, 2008, which later formed an alliance with opposition Republican and New Rights parties.
