That was quickly proven when Trierweiler tweeted her support in legislative elections for an independent rival of Royal, with whom the First Lady did not have a warm relationship.

Hollande is the second French president to split from his partner while in office.
In 2007, his predecessor Sarkozy divorced his wife, Cecilia, and married former supermodel and singer Carla Bruni the following year.
Hollande, who is France’s least popular president according to opinion polls, has never denied an affair with Gayet, but has so far steadfastly refused to answer questions about his love life.
