The National Rally party is leading in the first round of elections with 34.2%, followed by the left-wing New Popular Front alliance and Macron's centrist coalition with 29.1% and 21.5%, respectively.
"We have made a decision that concerns more than 60 constituencies. It implies the withdrawal of our candidates. Their possible third place would lead to the victory of a lawmaker from National Rally over a candidate from another party who shares the values of the republic, as we do," Attal said on Sunday.
At the same time, the BFMTV broadcaster reported, citing data from the French Interior Ministry, that at least 37 lawmakers representing the National Rally party were elected in the first round of parliamentary elections.
