Analysis: The political crisis in France has deepened with the far-right National Rally threatening to block any prime ministerial candidate from the leftist New Popular Front. This has narrowed President Emmanuel Macron's options for resolving the deadlock caused by the inconclusive snap legislative election. The New Popular Front, a coalition of parties ranging from moderate Socialists to far-left groups, has argued for their candidate to be named prime minister, while Macron is considering other options such as a conservative regional president or a former Socialist Prime Minister. The situation remains uncertain as Macron seeks a candidate with broad appeal who can win approval from lawmakers to avoid further political turmoil.
