Tiphaine Auzière, 32, said 'jealousy' was behind the 'abhorrent' attacks targeting her 64-year-old mother's relationship with the French president, 39, in recent weeks.
The married lawyer defended Mrs Trogneux while promoted her own career as deputy to a parliamentary candidate for Mr Macron's new party. Mrs Auzière, a mother of two, said: 'I don't want to give credence to people who do this kind of thing.
'I find abhorrent in France in the 21st century such attacks, which would not be carried out against a male politician or a male companion of a female politician.'
'There's a lot of jealousy,' she concluded.
