Almost two-thirds of people in the Netherlands are in favour of continuing to support Ukraine financially, two years after Russia began its full-scale invasion, according to a poll for RTL Nieuws.

The survey of 19,000 people also found that the same proportion viewed Russia as an “enemy of the Netherlands” and 40% believed Vladimir Putin was likely to launch an attack on a Nato member state.

Despite the sympathy for Ukraine there is pessimism about the progress of the war, with only 3% of people saying they felt the country’s situation had improved in the last year while 43% believe it has got worse.

RTL pollster Gijs Rademaker said that many voters were concerned about the impact of Donald Trump returning to the White House if he wins the US presidential election in November.

“He has repeatedly said he will not help if a Nato country is attacked. I think half of people don’t believe he’s bluffing,” Rademaker said.

Overall 55% of people backed the current level of financial support for Ukraine while 9% wanted to give more. 15% were in favour of reducing the amount and 13% wanted to stop altogether.

Only four in 10 PVV voters were in favour of maintaining or increasing support, compared to 87% of PvdA-GroenLinks voters.

Three-quarters of Socialist Party (SP) voters were in favour, even though the party declined to sign a motion in parliament last week calling for the Netherlands to continue backing Ukraine “for as long as necessary”. The PVV and orthodox Christian SGP were also not among the signatories.
