The European Union "should not be kept in limbo for too long" over Britain's vote to leave the bloc, Swedish Prime Minister Stefan Lofven said Monday.
"You can't wait for too long, and have uncertainty," Lofven said after a meeting with the four centre-right Swedish opposition parties that support EU membership.
"Britain and the EU need to prepare, and I think the EU can begin to prepare for the courses of action that exist so that we are prepared," he told reporters.
Lofven said that while it was not possible to detail how many days or weeks were reasonable to wait before Britain invokes Article 50 of the Lisbon Treaty that opens talks on Brexit, it should not take too long.
"The EU shouldn't be kept in limbo for too long. If Britain has taken this decision, the political leadership has to take responsibility. It is worrying that we have not seen signs of that," he added.
Karin Enstrom, who represented the opposition conservative Moderate Party, said "the EU has to stick together" while opposition Centre Party leader Annie Loof urged the Swedish government to play an active role in the coming talks as Sweden needs to secure good future ties with Britain, she said.
Several cabinet members were also present at the meeting, including Finance Minister Magdalena Andersson and Isabella Lovin, minister for international development who is also co-leader of the Greens, junior coalition partner to Lofven's Social Democrats.
