This sort of question needs to start with some historical context in order to frame your answer. I would therefore start by talking about the origins of one nation conservatism. Throughout my answer it is important to link key concepts with key thinkers and politicians. The question requires more than just a simple definition of one nation conservatism; in order to achieve full marks one must examine how one nation conservatism has developed over time. Having said this a great way to start your answer is with a definition, this again helps frame the question.For example: 'One Nation Conservatism is a brand of Conservatism first outlined by Disraeli in the mid-19th century which attempted to broaden support for the Conservative Party by uniting the British people who were clearly divided by class differences'. Already I have addressed the key terms of the question and linked it back to a key thinker in conservatism. Throughout your answer it is important that you use key terms, where appropriate, in order to achieve full marks.I would develop my answer by giving more recent examples of one nation policies in action, this is key in order to achieve the highest marks available. For example: 'The 2015 Queens Speech was branded a One Nation programme by Cameron and senior government ministers due to the outlined commitment to health care spending. This is an example of the idea of 'safety net welfare'; this being a welfare system that ensures the safety of the most vulnerable in society'.The key to this sort of question is linking political theory to political practice.
