Greste's shocking show trial, PM Abbott must put all diplomatic options on the table - Milne

Greens Leader Christine Milne says the Prime Minister should immediately intervene with the Egyptian President and consider all diplomatic options regardless of any avenues of appeal being followed by the Greste legal team.

"This has been a shocking show trial. It is a terrible day, not only for Peter Greste and his family but for the free press across the world," Senator Milne said.

"I have zero confidence in the integrity of the Egyptian legal system that has imprisoned journalists for reporting the news, and which sentences protesters to death.

"Prime Minister Tony Abbott and Australia must now lead international action to intervene with the Egyptian government to secure the release of Peter Greste and void this ridiculous verdict.

"All diplomatic options, including sanctions, should be on the table.

"If Egypt wants any hope of re-joining the international community with any standing or respect, it must stand for a free press and release Peter Greste and his colleagues immediately."
