It remains unclear exactly how the right-wing government plans to pay for its spring spending plans, but some ministers are known to be unhappy about the outcome.

Although the current cabinet is supposed to be “extra-parliamentary”, meaning ministers take decisions independently of the four parties, it was the four party leaders who drew up the contours of the agreement, culminating in a marathon 25-hour session.

The cabinet did agree to the plan on Thursday, and more details about the financing are due to be published later on Friday.

What is clear so far is that income tax will not be lowered as much as planned, free childcare will be postponed from 2027 to 2029, some ministry budgets will not be index-linked for inflation, and reserves to build a railway line between Lelystad and Groningen have been depleted.

Prime minister Dick Schoof told reporters on Thursday that ministers should not have been surprised by the decisions, given that finance minister Eelco Heinen has been working on the plans since January.

However, climate minister Sophie Hermans is said to be furious about the decision to cut her budget to pay for a €20-a-year reduction in domestic energy bills. Hermans described the move as “short-sighted”.

Prisons minister Ingrid Coenradie has also criticised the decision not to allocate more funding to solve the shortage of cells and to bring in the “tougher sentences” that the coalition partners have agreed on. “I don’t see how this can be done with zero budget,” she said.

The junior minister, who represents the far-right PVV, had asked for a €400 million budget boost.

It has also emerged that social affairs minister Eddy van Hijum, a minister on behalf of the NSC, threatened to resign if the four party leaders decided to cut his budget during their talks.
