Liberal Party leader Jan Björklund told Swedish Radio News that Sweden should participate in the fight against IS and that both the US and France have asked for the Nordic nationa to provide fighter jets.
According to Björklund, the Jas aircraft could be used either for aerial reconnaissance or in armed military campaigns.
"We shouldn't be refusing one thing or another," said Björklund. "Those are the needs that exist and so we should meet the needs."
Negotiations over Sweden's involvement in the fight against IS are in the final stages. But the four centre-right Alliance parties and the centre-left government will continue their talks tomorrow, Wednesday, Swedish Radio News reports.
The last time Sweden provided Jas Gripen fighter jets to an international military mission was in Lybia in 2011. Those aircraft were used for reconnaissance only and were not allowed to be used for attacking targets on the ground.
This time around, the Alliance does not want to rule out armed attacks and those could take place both on Syrian and Iraqi territories, said Björklund.
Swedish Radio News has reached out to the government for a comment.
Sweden's centre-right Alliance opposition is made up of the conservative Moderate Party, the Liberal Party, the Christian Democrats and the Centre Party. Sweden's coalition government is made up of the Social Democrats and the Green Party.
