PARIS, June 25 Reuters The prospect of a politically extreme party with little or no government experience taking power after France39;s parliamentary elections is worrying investors, the chief executive of Paris stock market operator Euronext said on Tuesday.

The farright National Rally RN party looks set to win the most votes in snap parliamentary elections coming up on June 30 and July 7 and could form France39;s next government, with a leftwing coalition called New Popular Front forecast to come second.

If a team that has never governed comes to power, there is total uncertainty, a complete unknown, Euronext CEO Stephane Boujnah told France Inter radio in a rare comment about politics.

There is also a lot of concern about other things that are not economic, for example about what is happening to the unity of French society and the risks that this unity, which could be damaged, could have an impact on business, he added.

Seeking to cast his centrist camp as the last hope for stability, President Emmanuel Macron said in a podcast released on Monday that both the RN party and the New Popular Front risked bringing civil war to France.

RN leader Le Pen on Tuesday rebuffed these allegations.

I think the French have realised that the chaos is him Macron, he has embodied chaos since he was first elected, she told RTL radio.
