The UK as an EU member could still have given the exact same amount as they have given outside of it. They could have done that either by cutting spending in other areas, raising taxes or borrowing more. Whether or not they would have is a very hypothetical/speculative counterfactual which nobody can know either way with any great confidence. > The UK was one of the leaders in within the western EU and had to act in coordination with the rest of the EU There is no hard requirement to "act in coordination with the rest of the EU". In the area of foreign policy, the EU has no enforcement mechanism. In other policy areas, if a member state disobeys EU rules, the Commission can take them to the European Court of Justice; however, foreign policy has been explicitly excluded from the Court's jurisdiction. So if the UK really wants to do their own thing on foreign policy, there is nothing the EU (or its other members) can do to stop them.
