Fiona Scott Morton was recently appointed as chief economist in the Commission's Directorate-General (DG) for Competition by European Commissioner for Competition Margrethe Vestager. This started a series of complaints by numerous French politicians based on the fact that she is American and has been a consultant for American tech giants.
Given Margrethe Vestager's record of fining giant multinational companies, it seems strange that she would nominate someone who might be soft on them. Also, the fact that the complaints come mostly from one country only makes me think that some other realpolitik reasons might be at play.
Are my doubts justified? If yes, what could be other reasons for France opposing this nomination?
