Former French prime minister Manuel Valls said Tuesday he was leaving the Socialist Party, with a source adding that he would now be allied to President Emmanuel Macron's centrist group, reports Yahoo! News.
"Part of my political life is coming to an end. I am leaving the Socialist Party, or the Socialist Party is leaving me," the 54-year-old told RTL radio.
Valls, who was prime minister under Socialist president François Hollande from 2014 to 2016, was rejected by Socialist voters in the party's primary to choose a candidate for this year's presidential election.
The party chose hard-left candidate Benoît Hamon instead and he failed to reach the run-off of the presidential election in May as France's two main parties fell at the first hurdle for the first time since 1958.
Macron's Republic on the Move (REM) party won a commanding majority in the legislative elections that followed.
The Socialists were humiliated and won just 30 seats as voters punished the party for five years in power overshadowed by sluggish economic growth and high unemployment.
Valls had approached REM about running as a candidate in the legislative elections but in the end an arrangement was reached under which REM did not field a candidate against him.
