Undertaking a transatlantic dialogue on regionalism and its implications for rural policy is challenging. First, our research highlights important differences in understandings of what is meant by regionalism. What is described as regionalism in the US and what is meant in the UK are very different in terms of scale and process. Second, distinctions within the devolved UK means that regionalism can only be meaningfully talked about in the English context rather than in the UK overall. However, while its importance is largely confi ned to England, regionalism has had major implications for the development and delivery of rural policy over the last decade, which makes it an important dimension of rural transformation in the UK more generally.
