The blurb that comes with this photo doesn't make it obvious who is who, so I did a little more digging. Defferre was a member of the French Section of the Workers' International at the time (and later became a member of the socialist party in 1969) and is the Mayor of Marseille, Ribière (the one with the darker hair in the photos) is the Socialist Party Candidate for president. Absolutely fascinating.
