Converting permanent residence permits into temporary ones, even retroactively, was a priority for the Sweden Democrats in the Tidö Partnership, the governing agreement where the far-right Sweden Democrats (currently the largest right-wing party in parliament) provide support to a Moderate-led government in exchange for the implementation of their party's policies.

But after a proposed law to strip people of permanent residency status was received widespread criticism – including from lawyers calling it "illegal" and "simply stupid" and even the Swedish Migration Agency – it was shelved.

In an interview with TT in June, Jimmie Åkesson downplayed the importance of the issue for his party and and said that it was "not a big issue."

Now, however, he says that he has "hard to see" that it wouldn't be implemented if the Tidö parties win the election, and that he expects a new negotiation between the parties on how it can happen.

"We have given quite a few people permanent residence permits, a kind of citizenship, but without the obligations that come with citizenship. I don't think it's reasonable," he said.

Liberal Party leader Simona Mohamsson has said that her party will not agree to the proposal. But according to Jimmie Åkesson, the four Tidö parties have agreed to "go in that direction".

"We will not be able to convert all permanent residence permits, but a lot can be converted," he told Sveriges Radio.

Åkesson also said that if he party is re-elected to a position of power he wants to see all funding for integration cut.

"I would like to spend exactly zero kronor on integration," said leader Jimmie Åkesson. "It is not a question of money, it is a question of individual responsibility to adapt to society or not," he said in an interview with public radio programme Sveriges Radio Ekot.

He believes that those who do not want to adapt can move somewhere else.

"If I go to another country and intend to live there permanently, I do not expect to get a lot of benefits from that country, but it is up to me whether I want to establish myself in that country," he said.

Åkesson also says that he does not see any major reforms ahead of him in the next term when it comes to immigration.

"We probably have the most restrictive asylum legislation in Europe right now, it is difficult to get any further," he said.
