The leader of Sweden’s third-largest party said he has not yet been able to reach a deal in his talks to form a coalition government, and has been granted a two-day extension to broker an agreement.

After two weeks of talks with other centre-right parties, Moderates leader Ulf Kristersson said: “We are moving towards the formation of a new government in the coming days. There are some details we want to clear up.”

It was not clear which parties would be part of centre-right governing coalition and he declined to elaborate on what “details” need to be dealt with.

He met on Wednesday with Andreas Norlen, the speaker of the 349-seat Swedish parliament, to report on his progress.

Later, Mr Norlen said in a statement that he had agreed to give an extension until Friday.

In Sweden’s September 11 election, the country’s four centre-right parties won 176 seats while the centre-left coalition that included the ruling Social Democrats got 173 seats.

Following that, Mr Norlen asked Mr Kristersson to see if he can form a governing coalition.

In the past two weeks, he has held talks with the populist Sweden Democrats, the Liberals and Christian Democrats.

The Liberals party does not want to be in a coalition with the right-wing Sweden Democrats, a party founded in the 1980s by far-right extremists that now is the country’s second-largest group in parliament.

In recent weeks, the populist party that wants to crack down on crime and strictly limit immigration, has tried to move toward the mainstream.

A vote in parliament on a new Swedish prime minister is likely set for Monday October 17.

Days after the elections, Swedish Social Democratic Prime Minister Magdalena Andersson who heads Sweden’s largest party, acknowledged losing the election.

She will continue in a caretaker capacity until a new government is formed.
