Denmark's far-right topped opinion polls Friday as the nation's once dominant Social Democrats crashed in popularity.

The Dansk Folkeparti or Danish People Party - once the butt of jokes - was the biggest winner as voters deserted the old centre-left certainties.

The poll, in the daily newspaper Politiken, put the Folkeparti on around a fifth of the vote, about the same as they got in last year's general election.

But the Social Democrats lost a quarter of their support, plunging below 20 per cent in what one Politiken analysts referred to as a "negative tsunami".

Denmark's Social Democrats are now polling even lower than their Scottish sister party, Labour, after their 2015 Tsunami.

The reason for their decline: backing asylum policies seen as brutal in much of the rest of Europe.

Politiken ran a cartoon showing Social Democrat leader Mette Frederiksen looking out of her window on a multi-cultral street with a red rose, symbol of her party, wilting in a jar.

The Herald:

Their fate comes after party MPs backed Denmark's highly controversial laws confiscating valuables from refugees.

Human rights activists have denounced the move as degrading and inhumane.

The Danish government says it is simply applying the same rules to migrants as to Danes who receive social benefits.

But the row has propelled Denmark - usually seen as a bastion of Nordic tolerance and relaxed "hygge" cosiness - in to the international limelight.

Speaking of the new law, he said: "Basically it's an insult to human dignity to have that kind of policy."

The world media poured scorn on Denmark, with one cartoon in The Guardian portraying Prime Minister Lars Loekke Rasmussen as a comedy Hitler.

The Guardian wasn't the first do put some hair on Mr Rasmussen's lip. Last year Egyptian-born Danish stand-up comic Omar Marzouk did the same.

The Herald:

The result of this world attention: significant soul-searching; a rejection off the Social Democrats; and a rise in support for parties opposed to the new law.

Alternatives, a new party, has nearly doubled its support to more than nine percent support .

Party leader Uffe Elbaek told Politiken: "This represents a huge rift in society."

The Dansk Folkeparti - parodied in the hit TV series Borgen as the Freedom Party featuring gauche leader Svend Åge Saltum in the video below - gained just one per cent. Mr Rasmussen's centre-right party Venstre lost one point.

The Social Democrats dominated Danish politics in the 20th century. The party's Helle Thorning-Schmidt, the daughter-in-law of Neil Kinnock, was prime minister until last year. Ms Thorning-Schmidt, pictured below with David Cameron, left politics this month to become chief executive of Save the Children.
