The Author examines the new European legislation concerning the protection of retail investor in case of the insurance-based investment product trying to highlight the main questions deriving from that legislation. First of all, he considers the different rules regarding the above mentioned protection which are in different directives as MiFID II and IDD to underline, on one hand, the convergence of rules and, on the other hands, the difficulties to make an effective control on those products given the existence of different financial supervisory authorities (i.e. EIOPA and ESMA) for homogeneous products. A possible solution has offered by European regulation about the PRIIPs.
