A former conservative minister and several French MPs are calling for a parliamentary inquiry into links between Steve Bannon, Donald Trump’s former advisor, and Marine Le Pen’s far-Right party.

Frédéric Lefebvre, who served as trade minister in the centre-Right government of President Nicolas Sarkozy, is urging the French parliament to investigate whether the anti-immigration party is guilty of “collusion with a foreign power”.

Mr Lefebvre made the demand in an open letter to the heads of the National Assembly’s law and foreign affairs committees after the public television channel France 2 revealed alleged close links between Ms Le Pen’s party and Mr Bannon.

A number of conservative, centrist and Socialist senators and members of the National Assembly are backing the call for an investigation into whether Mr Bannon’s relationship with the party constitutes illegal foreign meddling in a French election.

The France 2 report used previously unaired footage from an American documenary maker, Alison Klayman, showing Ms Le Pen’s partner Louis Aliot and another senior party official offering to let Mr Bannon attend meetings between Ms Le Pen and high-ranking French civil servants. Ms Klayman is making a film about Mr Bannon.
