It evaluates several political commentators, as B. T. has spoken with.

"immigration policy is a political battleground in the Left. There are two wings, and if Jakob Ellemann should be prime minister, he must have tied a bow on it. He doesn't get the power, if he has uncertainty on immigration policy. And that he has right now," says Michael Kristiansen, who is a longtime political commentator at TV 2 News.

Several years of internal strife in the Left was attempted shelved with the election of Jakob Ellemann-Jensen as the new president, but on Friday threw out the Left-member Marcus Knuth a bomb in fløjkrigen, when he on Facebook told that he is leaving the Left.

"We must speak openly and critically about the role of islam in the Danish society, just as we must hold fast to Denmark based on freedom, christian values. The battle can I best fight as part of The Conservative Party, where værdipolitikken is it that brings together – not what divides," writes Marcus Knuth in a posting on Facebook, where he takes leave of the Left.

Partiskiftet comes as a big surprise to the political commentators, B. T. has spoken with. They agree that Jacob Ellemann-Jensen is faced with a big problem.

"It shows that fløjkrigen on immigration policy is far from over. It's going to continue for a long time. It is very Betpark harmful for the party," says Erik Holstein, a political commentator for the Althing.

He believes that Marcus Knuths partiskifte can also be motivated by personal ambitions.

As udlændingeordfører in Lars Løkke Rasmussen's government marked the Marcus Knuth himself as a tough dog in the aliens policy.

In the debate on the burkaforbuddet he was one of the warmest supporters of a ban, and his rhetoric in the debate was supposedly the reason why his was stripped of his ordførerskab in the area. Instead, he is now appointed to Grønlandsordfører.

Marcus Knuths exit is a loss for the wing in the Left, who advocates a harder course in immigration policy. The wing will be led by vice-president Inger Støjberg, and she is now weakened back in the Left, assesses B. T.'s political commentator, Sea Marie Serup.

"Støjberg loses his faith squire and wingman. He has backed her up in everything she does. It makes Mads Fuglede also. They have had a threesome, which now becomes a tokløver," says the Sea Marie Serup.

B. T. called Emil Winckler, who is personal advisor to Inger Støjberg, to hear her comment to Marcus Knuths criticism of the Liberal party relax immigration policy.

"Call Jakob Ellemann," saith the spindoktoren.

But it is Inger, I will have a comment from.

"It makes you not. Call Jakob Ellemann."

B. T. have tried in vain to get a comment from Jakob Ellemann-Jensen. To the news agency Ritzau he says that he is sorry that Knuth leaves Left.

He rejects at the same time, there is talk about a fløjkrig on immigration policy in the Left.

"I think frankly, that there are insurmountable political differences in the Left. We carries out the policy, as we all together went to the election on," says Jakob Ellemann-Jensen, to Ritzau.

B. T. have also tried to get a comment from Marcus Knuth, but he has not answered our request.
