PARIS (AFP) - President Emmanuel Macron is to address France on Wednesday (June 22) over the crisis created by his failure to retain a parliamentary majority, with no solution in sight to an impasse that jeopardises his reform plans.

Mr Macron's centrist alliance finished Sunday's parliamentary elections 44 seats short of a majority in the National Assembly, as a new left-wing coalition and the far right made major gains.

The situation has called into question Mr Macron's plans for reform in his second term after his April presidential re-election - including a key measure to raise the retirement age - and risks denting his international stature.

Mr Macron, who until now has kept a careful public silence on the deadlock, will make a televised address at 8pm (2am on Thursday, Singapore time), his office announced.

Over the past two days, he has hosted rare talks at the Elysee Palace with opposition leaders to find a way out of the crisis.

He met the head of the far-right National Rally (RN) Marine Le Pen on Tuesday, while the head of the left-wing NUPES alliance, hard-leftist Jean-Luc Melenchon, sent MP Adrien Quatennens, 32, to represent him in talks on Wednesday, in a clear snub to the President.

The meetings so far appear to have made little headway, and Mr Macron has also rejected an offer from under-fire Prime Minister Elisabeth Borne to resign.

"The unfindable compromise? Emmanuel Macron is trying to regain the initiative but no consensus has been found," said the right-wing Le Figaro daily.

National unity government?

Mr Macron's intervention on Wednesday will be crucial for indicating his future strategy, especially as he is to be distracted by foreign policy and outside of France for much of the next week.

He is due to attend a European Union summit on Thursday and Friday, then the Group of Seven summit in Germany from Sunday and then the Nato summit in Madrid from next Tuesday.

Analysts have said the most viable solution would be a deal between Mr Macron's centrist alliance and the right-wing Republicans (LR), a party on the decline but which still won 61 seats.

But after talks with Mr Macron on Tuesday, LR leader Christian Jacob ruled out any kind of "pact" with Mr Macron's Together alliance.

Former prime minister Edouard Philippe, whose Horizons party is part of Mr Macron's alliance, told BFM television late on Tuesday that a "grand coalition" should now be formed.

"We need to hear what the voters have said and take them seriously," he said.

Communist party chief Fabien Roussel, who is part of the NUPES alliance and held talks with Mr Macron on Tuesday, said after the meeting that the President had evoked a "government of national unity" as a way out of the impasse.

'All options' on table

Speaking as she introduced new MPs at Parliament on Wednesday, Ms Le Pen said the President had floated the same idea with her.

Mr Olivier Veran, the minister in charge of relations with Parliament, told BFM on Wednesday that "all options" were on the table.

But he ruled out working with Ms Le Pen's RN or Mr Melenchon's France Unbowed (LFI) to find a majority.

This could be achieved, he said, either through an alliance or on a "Bill by Bill" basis, with the government finding a majority thanks to certain MPs on the right or left, depending on the legislation.

Mr Julien Bayou, the leader of the Green EELV party that is part of NUPES, said after his talks with Mr Macron on Wednesday that his party would be in opposition.

But it would vote "according to the national interest" and would put forward its own legislation on climate change.

Mr Melenchon has threatened to file a motion of no-confidence against Ms Borne next month, but other opposition leaders have shown less appetite for such action.

Ms Borne, an experienced technocrat with little experience of front-line campaign politics and in office for just over month, has been widely criticised for her performance in the election.

While Mr Macron has rejected her offer to resign, her future remains in question.

Mr Francois Bayrou, a key Macron ally who leads the MoDem party that is part of his coalition, increased the pressure on Ms Borne on Wednesday.

France needs a "political" prime minister, he said.
