Talks have begun between the four coalition parties to discuss Geert Wilders’s demands to bring in stricter rules to bring down the number of asylum seekers entering the Netherlands.

Wilders took the unusual step of calling a press conference on Monday to announce a 10-point plan of measures to cut immigration, including using the army to patrol the borders and sending all Syrian refugees home.

He warned that his PVV party could withdraw from the coalition unless the cabinet delivered results within “a few weeks”.

Wilders’ demands are expected to dominate Tuesday’s regular meeting between the four leaders of the coalition parties at Wilders’ parliamentary office in The Hague.

The other three partners were critical of Wilders and the PVV-appointed minister for asylum and immigration, Marjolein Faber, who has struggled to realise the party’s promises to implement the “harshest asylum regime ever”.

“We could have got a lot further if the PVV minister had delivered on the permanent solutions that we previously agreed,” said Queeny Rajkowski, asylum and migration spokeswoman for the right-wing liberal VVD party.

Nicolien van Vroonhoven, leader of the centre-right NSC, said she saw no reason to renegotiate the outline coalition agreement from last July, which included a number of measures to restrict migration.

“That agreement was a carefully balanced document. We’re not going to renegotiate it just like that,” she said. “He can keep reheating his plans all he like, but that’s not how it works.”

Caroline van der Plas, leader of the farmers’ party BBB, did not comment directly on the PVV leader’s proposals, but said the coalition needed to agree a way forward “quickly”. Asked if she was worried about the cabinet collapsing, she replied: “Not at all.”
