Donald Trump has leapt from political laughing stock to the President-elect of the most powerful office in the world. The US is a vital partner of UK businesses, accounting for 12% of UK retail exports. The UK is also the largest foreign investor in the US and its retail sector is influenced by the US economy which, until now, has been quite stable. With Brexit cutting many important trade relationships, the UK’s most important trade and political partner could now either be a lifeline asset or a liability as signs point towards isolationism. The most significant parallel between America’s election and the UK’s Brexit is that there is no way to predict what will happen as both countries and their respective economies venture into unexplored territory.
