Prime Minister Pedro Sánchez, in a letter to NATO Secretary-General Mark Rutte, said Spain 'cannot commit to a specific spending target in terms of GDP' at next week’s NATO summit in The Hague.

Spain has asked to opt out of NATO's plan to increase members' defence spending to 5% of their gross domestic product, a move that could derail a summit at which the military alliance plans to ask them to commit to the target.

Spain has rejected a NATO proposal to spend 5% of GDP on defense needs that’s expected to be announced next week, calling it “unreasonable.”
