French authorities were searching the mayoral offices of former French Prime Minister Edouard Philippe - also the mayor of Le Havre - as part of a preliminary investigation linked to possible corruption and financial wrongdoings, a judicial source said on Wednesday.
Philippe, who is widely seen as a potential candidate to succeed Emmanuel Macron in France's next presidential election, could not immediately be reached for comment.
French paper Le Monde earlier reported the probe is targeting Philippe directly, as well as some of his aides.
