CAIRO, Nov 25 (Reuters) - Egyptian Justice Minister Ahmed Mekky has started mediation efforts to try to end a crisis between Egypt's executive and judicial authorities, state TV reported on Sunday.

It was the first public sign of a government attempt to resolve a crisis ignited by President Mohamed Mursi's decision to expand his powers and protect his decisions from judicial review.

Mekky, who has said he has "some reservations" about Mursi's decree, convened a meeting at the Supreme Court headquarters in Cairo, state TV reported, without giving further details.
