PARIS   -   French Prime Minister Gabriel Attal was set to resign but stay on as head of a caretaker government Tuesday, officials said, with no replacement in sight as divided parliamentary groups succumb to infighting.  President Emmanuel Macron is expected to accept Attal’s resignation after Tuesday’s cabinet meeting -- the first since his allies got roundly beaten in a snap National Assembly election called to “clarify” the political landscape.  But he was also likely to ask the prime minister and his team to stay on as a caretaker government with restricted powers until after the Paris Olympics, which open on July 26.  This would also give political parties more time to build a governing coalition after the July 7 election runoff left the National Assembly without an overall majority.  A broad alliance -- called New Popular Front (NFP) -- of Socialists, Communists, Greens and the hard-left France Unbowed (LFI) won the most seats, with 193 in the 577-strong lower chamber.  Macron’s allies came second with 164 seats and the far-right National Rally (RN) third at 143.
