Left Party " ;Unyielding France" announced on Tuesday legislative steps aimed at reversing President Emmanuel Macron's pension reform, including the increase in the retirement age from 62 to 64, News.bg quoted.
"National Assembly" (NC) quickly offered its support for the legislation proposed by "Adamant France" (NF), which may increase the chances of parliamentary approval.
Repealing the pension reform signed last year aimed at protecting state finances and increasing productivity is a key goal of the left-wing camp, which emerged last month as the strongest parliamentary force after early elections.
But the left camp failed to win a majority in the election, leaving it dependent on the support of other lawmakers to push through the new legislation.
"Today we will present a legislative proposal to cancel the pension reforms," Mathilde Pano, who heads the group of NF MPs in the National Assembly, told France Inter radio.
Macron's decision to use special constitutional powers to raise the retirement age and remove some privileges for certain job categories led to violent street protests last year.
"National Assembly" Marine Le Pen's (NC) also campaigned to lower the retirement age, while Macron's centrist bloc and other centre-right politicians said they would oppose such a move.
This bill will not pass without the votes of the "National Assembly". "By sticking to our program, we will vote for him,", NA spokesman and MP Laurent Iacobelli told BFM TV.
"Your law will pass thanks to us... and you will have to say it clearly and publicly," he added.
However, the members of the left coalition may not participate in the vote, which can only pass with the support of right-wing MPs.
While leftist parties have repeatedly said they are united in their determination to lower the retirement age, LFI's partners in the "New Popular Front" - which includes the Socialists, the Greens and the Communists - can abstain from a vote that will pass only with the support of right-wing MPs.
The bill, which is unlikely to be voted on before September, will not pass with the support of LFI and National Assembly MPs alone.
France has been in a state of parliamentary deadlock since Macron's decision to call the election, with the current government likely to serve in the summer as a government in resignation.
