Former Sri lankan Army chief Sarath Fonseka was on Sunday conferred the country's highest military rank of field marshal for "achieving victory over terrorism" by the new Government, five years after he was jailed on alleged treason charges by the previous regime. President Maithripala Sirisena awarded the honorary title to retired Gen Fonseka at an official ceremony in the Capital. Sirisena said ensuring justice for the 64-year-old former Army chief was a "responsibility undertaken by the Government in our quest for justice for the whole of the Army."
