French President Nicolas Sarkozy threatened to “smash the face” of an editor whose magazine suggested that his wife Carla Bruni was a maneater, a new biography alleges.
The outburst came when Mr Sarkozy harangued the editor by phone for 40 minutes in January 2008, it is alleged.
Excerpts from the book by Le Point director Franz-Olivier Giesbert appeared in French media on Friday.
There was no immediate comment from the French presidency on the revelations.
