French President Emmanuel Macron appealed Wednesday for "responsibility" from the opposition parties whose gains in last weekend's legislative elections dismantled the centrist majority in parliament.

"We must learn to govern and legislate differently," he said in a nationally broadcast address three days after Marine Le Pen's far-right National Rally enjoyed its greatest success to date and a new leftist coalition emerged as the main opposition.

At the same time, Macron said that he will not sacrifice the "coherence" of the agenda of "ambitious reform" he proposed ahead of his victory over Le Pen in April's presidential runoff.
