Here -
ryanair marseille base - Ryanair ferme mardi sa seule base française, à Marseille
are a series of vid links to various news outlets on RyR leaving MRS.
Not much more detail and little info on routes. MO'L did say he would reverse the flight pattern of a number of the MRS routes, presumably where he has aircraft based, hence Eindhoven loses and Edinburgh and Dublin will continue.
Personally I am surprised that they have dropped a number of flights to/from Morocco, they were, by all appearances, doing well there. Perhaps they'll open a few more in Summer, although I wouldn't have thought it was a big deal summer/winter as it was mostly expats living in France who travelled.
