Well, French polls seem to suggest that Macron will get a comfortable majority in upcoming legislative elections (maybe 300-400 seats out of 577). Right-wing LR could maybe get 100 (they have 200+ currently), Socialists & allies between 25 and 60 (compared to 280+), and maybe 5 to 20 seats for each far left FI and far right FN.
This is a massive problem for the Socialists, because the public financing of political parties are tied to the results of the election and for both LR and PS is the most important source for funding.
Political observers are now routinely expecting both the PS and LR to implode within the year. Far-left Mélenchon is pretty clearly trying to grind what's left of the Socialists to rise as the only leftist champion. Macron's success and the sudden emergence of a massive central bloc will maybe be the trigger for breaking the party in two between those ready to embrace alliances with the far-right and the others. It's all maybe a bit premature, however, as it's hard to have any certainties on how solid "Macronism" will be beyond the current wave and if it will gel as a real entity with a coherent ideology. And even at the verge of ruin, PS and LR have longstanding, solid networks which are in themselves valuable assets.
Meanwhile some controversy as the newspaper "Le Parisien - Aujourd'hui en France" claims to have had access to a draft of the upcoming labor law reform (or to be technical : a bill for the parliament to allow the government to use decrees instead of passing bills on the matter for a given period of time), going beyond what has been made public so far. Official sources denies it is a draft. Things should be made clear soon as union leaders will enter in discussions and negociations with the government shortly.
