So today there were a bunch of internal votes in the assembly. The new president of the assembly supports Macron (it was expected, they have the biggest number of MPs). The expected distribution for the other roles was :
Questure (those who overlook the parliament's finances) : 2 for Macron's people, 1 for the opposition, of which the largest voting block is the left.
Vice presidents (who preside the assembly when the president is busy doing other stuff, for example in very long sessions) : 2 for the left, 2 for Macron's people, 1 for the classic right, 1 for the far right.
Instead the right made a deal with the far right to get their candidate elected to the questure, and in exchange didn't try to get a vice president spot : which means that the left didn't get a questure and the far right got 2 vice president spots. All of this was validated by Macron's party in order to weaken the left, ending up strengthening the far right in the process.
