France's far-right National Front (FN) is set to dominate the country's regional assemblies in the upcoming elections as a result of persistent public discontent over the government's poor economic and financial scores, a poll has showed.

The far-right party would gain 29 percent of the votes, followed by the centre-right Les Republicans party whose candidates would garner 27 percent, Xinhua cited TNS Sofres-One Point survey as showing on Tuesday.

The ruling Socialists, currently dominating France's regional councils, ranked third with 22 percent of the votes despite a sharp rise in President Francois Hollande's popularity after Paris attacks.

At least 58 percent of the respondents said November 13 Paris attacks had no impact on their choice.

Challenging for power, the anti-immigrant National Front recorded unprecedented victory in European Parliament election and mayoral run-off in 2014, mirroring a rising public support for the far-right party to rule Europe's second largest economy.

The two-round regional elections are scheduled for December 6 and 13.

The poll surveyed 1,552 respondents from November 20 to November 23.
