Résume The local Galois representation attached to an ordinarycusp form of weight $2$ or more is reducible. It is expectedthat this representation is semi-simple exactly whenthe underlying form has CM. We shall describe some recentspecific and general attacks on this problem. In particularwe shall speak about some work in progress with Hida, whichbuilds on earlier work with Vatsal.
