Three centre-left parties – the Socialists, Greens and Communists – broke ranks with the more radical left LFI by taking part in talks with Macron.
However, they made clear they wanted a prime minister from the left, rather than a centrist.
“I told you I wanted someone from the left and the Greens and I think Mr Bayrou isn’t one or the other,” Greens leader Marine Tondelier told French TV on Thursday.
Patrick Kanner of the Socialists said that just because his party was not joining Bayrou’s government, “that doesn’t mean we’re going to bash it”.
Sébastien Chenu, a National Rally MP, said for his party it was less about who Macron picked than the “political line” he chose. If Bayrou wanted to tackle immigration and the cost of living crisis then he would “find an ally in us”.
Relations between the centre left and the radical LFI of Jean-Luc Mélenchon appear to have broken down over the three parties’ decision to pursue talks with President Macron.
After the LFI leader called on his former allies to steer clear of a coalition deal, Olivier Faure of the Socialists told French TV that “the more Mélenchon shouts the less he’s heard”.
Meanwhile, Marine Le Pen has called for her party’s policies on the cost of living to be taken into account by the incoming government, by building a budget that “doesn’t cross each party’s red lines”.
