Brigitte and Emmanuel Macron were a “vision of love”, according to the French first lady’s daughter, who has described how she watched her teacher mother fall for her teenage pupil.

Tiphaine Auzière, 34, has spoken in a television documentary for the first time about the love affair between her mother and the future president of France that began in the small town of Amiens in the 1990s.

Ms Auzière, the youngest of Mrs Macron's children from her first marriage, described in the programme how everyone could see that the married teacher had fallen in love with her precocious and ambitious 15-year-old pupil.

Ms Auzière was nine years old at the time.

“They were quite smitten and it was quite obvious between them and very difficult,” she said.

Brigitte Macron: A French Novel, which cements her image as the president’s mentor and muse, was broadcast on Wednesday, a year after she moved to the Elysée when her husband was elected president.
