Peter Witt, who held the rank of ambassador, will be able to use his first-hand experience to consult clients on crucial details of EU decision-making.
The press has written about GPlus Europe (which they display on their own website):
Within Brussels, one of the best-known cases of the seemingly organic ties between the EU institutions and businesses can be found in the sleek offices of GPlus Europe. Of the 49 employees listed on this public relations firm's website, 28 have worked for the European Parliament, the Commission or for the Brussels embassies of the Union's national governments.This is another example of important civil servants joining the lobbyist scene in Brussels, shortly after leaving public office. Whether this is much better than leaking secrets while being in office - I am not too sure.
GPlus has used the insider knowledge that its employees have of the EU institutions as a selling point, helping it to win clients as illustrious as Microsoft and Vladimir Putin; the former Russian president hired its services in an effort to improve his image in the West.
