I suspect De Gucht may have overestimated his influence here. He has also perhaps forgotten that his term of office is not so long and that the European Parliament could even hold up the appointment of the next Commission if it wanted to make a point about abuse of authority. (It did hold up the first Barroso commission in 2004, forcing a reshuffle of which commissioner was given which portfolio, so this is certainly not an idle threat for the Parliament to make, either.)
