Europe Ecology – The Greens
In 2016, Jadot was selected by Europe Ecology – The Greens to stand as their candidate in the 2017 French presidential election after defeating fellow MEP Michèle Rivasi in the second round of primary voting. Though Jadot secured 496 sponsorships just before the opening of the signature collection period, he announced that he would withdraw his candidacy and endorsed Socialist nominee Benoît Hamon, the pair having agreed on a common platform; their alliance was consummated when EELV primary voters approved the agreement on 26 February.
