NATO allies are pressing Spain to sign on to a stepped-up defense spending target and end a holdout that US President Donald Trump portrayed as unacceptable.

Spain has rejected a NATO proposal to spend 5% of gross domestic product on defense needs that’s expected to be announced next week.

Spain is threatening to derail a Nato summit intended to appease Donald Trump by refusing to commit to the US president’s request for allies to increase their defence spending to 5 per cent of GDP.
