France president Emmanuel Macron

Emmanuel Macron has won five more years as France's president after a convincing victory over rival Marine Le Pen, who nevertheless secured the far right's highest share of the vote yet.

He is the first sitting president in 20 years to be re-elected. More than one in three voters did not vote for either candidate

Centrist Macron was set to win around 58 percent of the vote in the second-round run-off compared with Le Pen on 42 percent,

He also pledged a "renewed method" to govern France, adding that this "new era" would not be one of "continuity with the last term which is now ending".

Mr Macron's victory was welcomed by relieved European leaders, who had feared a far-right candidate offering a series of anti-EU policies.

German Chancellor Olaf Scholz was first to congratulate him, singling out their mutual challenge in responding to Russia's war on Ukraine.

Mr Castex is now likely to be replaced in the next few days, and Mr Macron may ask Labour Minister Elisabeth Borne to take over.

Mr Mélenchon has already held out the prospect of defeating the president's centrist party and becoming prime minister.

Mr Macron chose a highly symbolic venue from the French Revolution for his victory speech in the Champs de Mars.

UK Prime Minister Boris Johnson also welcomed his victory.
