Thierry Breton, the French European Commissioner, has resigned from his position at the European Commission, citing "questionable governance" as the reason.

Breton's resignation comes after a public dispute with Commission President Ursula von der Leyen, who allegedly asked France to withdraw his candidacy for a second term.

Breton accused von der Leyen of making this request for personal reasons and offering France a supposedly more influential portfolio in return.

The resignation highlights ongoing tensions between Breton and von der Leyen, which have been simmering since Breton criticized her leadership style earlier this year.

This development adds complexity to the formation of the new European Commission team, as von der Leyen finalizes her list of commissioners following the recent European elections.
