PARIS (Reuters) - French President Emmanuel Macron paid a surprise visit to a Socialist-held working class suburb north of Paris on Wednesday on his first official outing since his re-election, in an effort to woo left-wing voters ahead of June's parliamentary vote.

       Macron strolled around a food market in the town of Cergy, shaking hands, chatting with young people and posing with them for selfies, in what the Elysee palace said was a way to show he was "listening to people's concerns, expectations and needs".

       Macron, a centrist, has long faced accusations of being too aloof and elitist, charges that discouraged some left-wing voters from backing him in Sunday's runoff vote against far-right candidate Marine Le Pen.

       "I want to give a message of respect and consideration to these areas that are among the poorest in the country right from the start of my new mandate," Macron told reporters in Cergy, where far-left candidate Jean-Luc Melenchon won almost half of the votes in the first round of the presidential election.

       RISING PRICES

       Sources close to Macron say he needs to counter the challenge mounted by Melenchon for the parliamentary elections on June 12 and 19, a crucial hurdle which will determine the president's ability to govern for the next five years.

       Melenchon, who came a strong third in the first round of the presidential vote after Macron and Le Pen, wants to rally a union of the left to dominate parliament and force Macron into an awkward "cohabitation".

       The cost of living has emerged as voters' number one priority in this year of elections, which coincide with sharp rises in food, energy and petrol prices partly caused by post-pandemic disruptions and by the war in Ukraine.

       Officials from working class areas say voters are particularly angry over rising prices of food staples including bread, rice and Ukraine-produced sunflower oil.

       "The most basic stuff is now very, very expensive," Mohammed Djae-Rachid, the head of the local Comorian community told Reuters TV. "Imagine that, a bottle of cooking oil used to cost one euro, now it's three euros. All the stores are empty, it's becoming very hard for everybody," he said.

       Macron's security detail at one point opened an umbrella to protect him against what appeared to be an attempt to pelt him with tomatoes on what was otherwise a friendly walkabout, where locals - many from an immigrant background - jostled excitedly to take pictures of themselves with the president.

       Asked who he would name as his prime minister, Macron said cryptically: "I will name someone who is keen to work on social, environmental and productive issues."
