Translate the following English sentence to French:
"First of all, regarding the remarks of Mr Crowley, who asked whether the second proposal could not simply consist in taking over a pure ISD approach; the objections of the Commission to that proposal would be the following: such an approach would pose difficulties which would arise from two different authorisations which may even involve different authorities and non-consistent sets of rules; moreover there would be no provisions whatsoever on conflicts of interest."
Premièrement, en ce qui concerne les remarques de M. Crowley qui a demandé si la seconde proposition ne pouvait pas simplement consister à calquer la directive sur les services d' investissement, voici les réticences de la Commission à cette proposition : une telle approche poserait des difficultés découlant de deux autorisations différences susceptibles d' impliquer différentes autorités et des ensembles de règles contradictoires ; en outre, il n' y aurait absolument aucune disposition régissant les conflits d' intérêt.
