The capital of France may be thousands of kilometers away from the battlefields of eastern Ukraine, but what happens in French voting stations this month could have repercussions there.

Far-right presidential candidate Marine Le Pen has close ties to Russia and wants to weaken the EU and NATO, which could undercut Western efforts to stop the war in Ukraine. Le Pen is trying to unseat centrist President Emmanuel Macron, who has a slim lead in polls ahead of France’s April 24 runoff election.

Here are some of the ways the election could impact the conflict:

ARMING UKRAINE

Macron’s government has sent 100 million euros worth of weaponry to Ukraine in recent weeks and said Wednesday it will send more as part of a Western military aid effort. France has been a major source of military support for Ukraine since 2014, when Russia annexed Crimea in 2014 and supported separatist fighters in eastern Ukraine.
