France's political future is uncertain as Marine Le Pen’s far-right National Rally (RN) leads opinion polls ahead of parliamentary elections on 30 June. Emmanuel Macron faces potential ‘cohabitation’ with an opposing prime minister, or a fragmented chamber unable to form a stable majority. The polls give RN at least 35% in the first round, with a left alliance at 29% and Macron's centrists around 20%. A high turnout is expected. RN could possibly win more than half the 577 seats being contested. Le Pen is already planning to challenge Macron's authority, especially regarding military decisions: her candidate for prime minister, Jordan Bardella, opposes sending long-range missiles to Ukraine. Current prime minister Gabriel Attal is seeking to highlight RN's divisiveness and the left’s sectarian policies. A final debate offers a last chance to sway voters.
