The Dutch government has pledged an extra €700 million in support for Ukraine from money left over in the defence and foreign affairs ministries’ budgets.

The cash is less than the €2 million demanded in a motion proposed in parliament by left-wing alliance GroenLinks-PvdA last week.

Prime minister Dick Schoof argued that the decision should be left to the next government, but parties with a majority of seats in parliament said they were prepared to support the motion on Tuesday.

The government has committed to give Ukraine €3.5 billion a year, but €2 million from the 2026 budget has already been donated this year. GL-PvdA and other parties said the current cabinet should make up the shortfall.

The €500 million surplus in the defence budget reflects delays to projects and the falling value of the US dollar against the euro, which has cut the cost of military equipment.

The foreign affairs department also has €200 million left over from its budget, most of it cash that was allocated to the European Peace Facility, a vehicle for military aid to Ukraine that has been blocked by Hungary.

Finance minister Eelco Heinen and defence minister Ruben Brekelmans warned in a letter to parliament that the Dutch government would “reach its limits” again next year.

But they wrote: “The cabinet continues to be committed to both military and non-military support for Ukraine and will carefully add more details to fulfil the motion by parliament at the start of next year.”
