The flight was en-route to ZZZZ from ZZZ. The flight was a crew of 4 pilots; and I was to be providing relief in the second half of the flight. I was awakened from rest to be brought back to the cockpit within the first hour or two to find the LE SLAT ASSYM message displayed on the EICAS and the working crew already taking the necessary steps. From this point; multiple calls placed to Company/Dispatch were made to decide the next course of action; and a Company/Crew decision was made to divert to a known maintenance facility: ZZZ. The applicable weather; NOTAMs; and fuel requirements were acquired from Dispatch for ZZZ and ZZZ1. Checklist procedures were followed and steps were taken to ensure the flight occurred within aircraft limitations. We ultimately made a safe; uneventful landing at ZZZ. LE FLAP ASSYM indication over ZZZZZ prompted to run checklist to solve the problem. Since the issue would not go away; a coordinated decision between flight crew and Company was made to divert to ZZZ.
During cruise; the leading edge slat asymmetry EICAS message and leading edge status lights illuminated. The aircraft handling and performance was normal in all respects. Close coordination with Company resulted in a company-directed diversion to ZZZ. We obtained weather; NOTAMS; and fuel requirements for ZZZ and ZZZ1; our new alternate. Landed uneventfully at ZZZ.
B767-200 flight crew reported that during cruise; they received a Leading Edge Slat Asymmetry message. Flight crew diverted and landed without incident.
