A common argument that is given for the continuation of the monarchy in Britain is that it provides the United Kingdom with soft power. The OED defines soft power as:
a persuasive approach to international relations, typically involving the use of economic or cultural influence.
To what extent is this argument valid? Can the amount of soft power provided by the Royal Family be measured in any way? Are there any prominent modern examples in which the monarchy has significantly affected the UK’s standing or status in the international community?
