PM still trying to save Chan and Sukumaran

Prime Minister Tony Abbott says he will make "every possible effort" to save drug traffickers Andrew Chan and Myuran Sukumaran from execution.

Chan and Sukumaran are due to face the firing squad after being denied presidential clemency from the death penalty.

Mr Abbott said he and Foreign Affairs Minister Julie Bishop had made representations to their Indonesian counterparts to save the two men and will continue to do so.

"Both men are reformed characters and both have helped to rehabilitate other prisoners," Mr Abbott said in a statement on Friday.
