With the track record of French politicians, it is no surprise that politicians would dislike paternity DNA testing!!!

From wikipedia regarding François Mitterrand [0]: He also had two children as results of extra-marital affairs: an acknowledged daughter, Mazarine (born 1974), with his mistress Anne Pingeot, and an unacknowledged son, Hravn Forsne (born 1988), with Swedish journalist Christina Forsne.
