As reported by The Local last week, the opposition parties are hoping to vote down several key parts of the law when it goes before parliament on Thursday, meaning the government risks a defeat on the last voting day of its parliamentary term.
"People are going to be given the choice of having an abortion or getting deported," Tony Haddou, an MP for the Left Party, said in a debate on Wednesday over the law. "That's the truth about this."
The law will require those extending a residency permit on the grounds of family reunion to meet maintenance and housing requirements for the first time, meaning, among other things, that if a family has another child they risk no longer meeting the requirements.
This same point was made this week on social media by both Centre Party migration spokesperson Niels Paarup-Petersen, and Green Party migration spokesperson Annika Hirvonen.
Green Party MP said the fact that families risk deportation if a parent loses a job or the parents have another child was "the most cynical" part of the new law.
Moderate Party MP Viktor Wärnick, when it was his term to speak, protested against what he described as a "loathsome" level of debate.
"It is reasonable to support your family if you want them in Sweden. Paarup-Petersen's style of debate should not be taken seriously and he should be ashamed of it," he said.
Ola Möller, an MP for the Social Democrats said that the the way the law had been framed risked hitting families hard if they, for instance lose their job or having another children.
"This policy is cruel," he said. "It builds deportations into the legislation itself as a recurring element."
Wärnick argued that by pushing against the new maintenance requirement for permit renewals the Social Democrats were making Sweden a more attractive country for migrants.
"It's important to bring in these new requirements so that Sweden deoes not become a more attractive country to try to get to than other EU countries," he said.
The party, he said, was pushing for the same sort of policies as the Spanish ones which had led to the crisis earlier this month in Ceuta.
"Here the Social Democrats are doing the same thing with the activists in the Left Party and the Green Party to increase hte pull factor."
