But what to do with the elder Mr. Le Pen has been a problem within the National Front for years, experts say. Mr. Le Pen founded the party 43 years ago and spent most of his energy running for president. His continued presence and history of controversial remarks have made it difficult for his daughter to rebrand the party and may have cost her the collaboration she sought with other more moderate far-right parties in the European Union.

When she hoped to work as a single caucus with the Dutch and British far-right parties, the leader of Britain’s U.K. Independence Party, Nigel Farage, shunned her, accusing her party of prejudice and anti-Semitism.

Mr. Le Pen, however, made clear that he would not be pushed aside without a fight. In his own statement, he said that when called before the executive board, he intended to express his views as a politician who is “responsible and ‘free’ and who always walks with his head up.”

In the meantime, he said, “each should take advantage of the delay to measure their responsibility to France, to the French and to the movement that embodies their hopes.”

The Le Pen family is famous for its living arrangements in the wealthy suburb of Saint-Cloud, west of Paris. Marine Le Pen lived on the family property, which includes gardens and several houses, until September. Her sister and mother, who is divorced from Mr. Le Pen, still live there. Mr. Le Pen now just keeps an office there.

When Ms. Le Pen, 46, finally moved out, apparently because her apartment in the former stables was too dark and small, the gossip magazine Closer wrote, “No more animated discussions with Daddy in the garden.”

Ms. Le Pen harbors her own presidential ambitions. But she has struggled to move out of her father’s shadow and distinguish her own reputation even as she tries to build a more mainstream party from the bottom up and field candidates in local elections.
