The French presidential fight shifted into higher gear Tuesday as Emmanuel Macron defended his sudden willingness to soften a pensions overhaul he has pushed for years, drawing accusations of a “ploy” to lure left-leaning voters from his far-right rival Marine Le Pen. Both candidates pressed their on-the-ground campaigns, with Macron holding a long walkabout in Mulhouse, eastern France, where the president was beaten out by far-left leader Jean-Luc Melenchon in the first round of voting last Sunday. Several residents assailed the centrist incumbent on pensions after he indicated the retirement age might be pushed back from 62 to only 64 — instead of 65 as long promised. “Yesterday I clarified things, if we need to be open to adapting this, I’m open to it,” Macron told journalists after a heated exchange with healthcare and other workers. “It’s normal that I should be ready to listen!” Since sweeping to power in 2017, the former investment banker has said an overhaul is necessary to keep the pay-as-you-go system afloat. But a series of massive strikes and then the Covid-19 pandemic forced him to put the plan on ice in 2020. But just last week his team had insisted that a retirement age of 65 was non-negotiable. Le Pen pounced on the shift as a cynical bid to woo the left-wing voters analysts say Macron needs in a tight run-off on April 24. She has promised a “social justice” campaign that would leave the retirement age at 62 — and even lower it to 60 for people who began working before the age of 20. “The French are very smart. Everyone knows this is a ploy by Emmanuel Macron to try to win over, or at least mollify, left-wing voters,” Le Pen told France Inter radio. “The reality is, retirement at 65 is his obsession. It’s all he has ever talked about,” she said. Meanwhile on Tuesday, Macron picked up a weighty right-wing endorsement from former president Nicolas Sarkozy, who broke months of campaign silence to say he would vote for Macron in the April 24 run-off. “We must abandon our partisan habits… Fidelity to right-wing republican values and our governing culture must lead us to answer Emmanuel Macron’s call for unity,” Sarkozy, who remains popular among many conservative voters, posted on his Facebook page. But the statement came just days after the candidate from Sarkozy’s own Republicans party — whom he refused to support publicly — was eliminated in the first round. Valerie Pecresse, budget minister in Sarkozy’s government, had made several attempts to secure her former boss’s blessing. Media reports claimed Sarkozy was unimpressed by her campaigning. But Sarkozy, convicted since leaving office of both corruption and illegal campaign financing, remains a scarecrow to many on the left and he might not help Macron’s effort to attract liberal voters.
