A day after an ''historic'' victory of Marine Le Pen’s Front National in the first round of regional elections in France, CRIF, the umbrella representative group of French Jewish institutions has called on voters to block the extreme right party in the second round next Sunday.

"On this coming Sunday go out and vote by the masses to block the National Front, a xenophobic and populist party. Do not allow the Republic to fall," the group said in a statement.

Jean-Marie Le Pen, the co-founder and former leader of the party, celebrated the party's’’historical’’ achievements in the elections Sunday by tweeting a video of Conservative party candidate Christian Estrosi wearing a skullcap and dancing with Jewish men.

"Take heart at a time of ill fortune," he said in a tweet accompanying the footage, which has since been removed.

Christian Estrosi is the conservative rival in the southeast to Jean-Marie's granddaughter and FN candidate Marion Marechal-Le Pen, who won more than 40% of the votes in the southern region of France.

Jean-Marie Le Pen has been several times convicted for racism and anti-Semitism.

Her daughter and Front National leader Marine Le Pen also broke the symbolic 40 per cent mark in the northern region, shattering previous records for the party as they tapped into voter anger over a stagnant economy and security fears linked to Europe's refugee crisis and the recent terror attacks in Paris.

The FN came first with around 28 per cent of the vote nationwide and topped the list in at least six of 13 regions.

A grouping of right-wing and center parties took 27 per cent, while the ruling Socialist Party of President Francois Hollande and its allies took 23.5 per cent.

Following Sunday’s historic score of the Front National, the Socialist Party has decided to withdraw his lists in three regions where it came third while rightist ‘Les Republicans’ party’s leader and former President of France Nicolas Sarkozy said he opposed a ‘’Republican front’’ with the PS against the FN.
