French first lady swipes at president's ex

France's first lady set the country's Twitter network alight on Tuesday with a good luck message to the parliamentary election rival of Segolene Royal, the Socialist politician who used to live with her partner President Francois Hollande. The message from Valerie Trierweiler entertained opponents of Hollande's Socialists and added a shot of venom days ahead of the June 17 ballot for the lower house of parliament, the National Assembly.
