Emmanuel Macron suffered a serious blow when his Environment Minister resigned, accusing the French Government of falling short on green issues and prey to lobbyists.
Nicolas Hulot, 63, a former TV wildlife presenter seen as the French equivalent of David Attenborough, was one of Macron's most popular ministers.
His appointment was hailed as a coup and he was one of only two in the Cabinet with the title of "minister of state".
However, after a little more than a year in office, he announced his resignation live on national radio, saying that neither the President nor his own wife were aware of his decision.
Hulot, who had voiced reservations from the outset, said he could no longer go on due to an "accumulation of disappointments".
