However, on Thursday afternoon, the opposition Social democrat leader Mona Sahlin said that she was deeply troubled by the government's acceptance of the scheme. All three opposition parties are are highly critical to the pipeline which they believe to be a dangerous project in a very sensitive area.
But Sahlin did not think it would be possible to scrap the co-operation should the opposition win the election in 2010.
"Legally I find it hard to believe that it would be possible. The matter had to be settled now- and I am afraid the government has gone about it the wrong way," she said to Swedish Radio News.
