This paper attempts to investigate the fiscal and budget reform initiated in the United Kingdom. In the first section, we illustrate the fiscal and budget reform initiated during 1990s and its relevant institutional arrangements. Then, we examine the fiscal data from the British government, including debt rate as of GDP, budget deficit as of GDP, and the budget structure of national government in the United Kingdom, so as to get recognized of the impact of these fiscal reforms in this country. Our study suggests that the performance in the United Kingdom after 1990s is relatively wholesome compared to most advanced economies in Europe.
