The leaders of the five parties currently involved in talks to form a new coalition government will continue their discussions this weekend after meeting together for the first time since the election, negotiator Sybrand Buma said on Friday.

Buma described Friday morning’s meeting as constructive and said it was important to have all five leaders at the same table. He acknowledged, however, that significant obstacles to forming a cabinet remain and said the party leaders carry a “major responsibility” to find a way forward.

“These five parties will have to make it work. The movement must come from them,” he said. Buma is due to deliver his final report to parliament on Tuesday, ahead of a debate scheduled for Wednesday.

Buma called the meeting for Friday morning after concluding on Thursday that there is currently no workable majority or minority coalition in the offing.

Several parties see enough common ground in the interim policy document drafted by D66 and CDA to continue talks, he said, but the key question now is “with whom”.

D66 leader and potential prime minister Rob Jetten said Friday’s talks took place “in a pleasant atmosphere” and gave all sides “plenty to think about” over the weekend.

VVD leader Dilan Yesilgöz, who has repeatedly said she will not join a coalition with the left-wing alliance GroenLinks-PvdA, said after Friday’s meeting that “more variations are possible”, without naming any specific combinations.

GL-PvdA leader Klaver will also continue talks in the coming days. He maintains that forming a minority cabinet would be the wrong choice and argues his party is needed, not least because of its position in the senate.

“Why would you talk to me about support in the upper house but not about participation in a cabinet?” he said. The right-wing coalition favoured by Yesilgöz is far from a majority in the upper house of parliament.
