Corporate governance is concerned with practical arrangements that seek to ensure that executive directors are not able to abuse their legal powers or any other in uence that they may have within their organisations. Consequently, corporate governance norms purport to regulate the day to day practice of corporate management. This chapter considers the Combined Code on Corporate Governance, which is the applicable code for public companies in the UK. It is not legally binding. Instead, such companies are intended to choose to conduct their internal processes in accordance with it, and the listing rules (within securities regulation, discussed in Chapter 11 ) require such companies to state whether or not they agree to be bound by it. We shall consider the key provisions of this code before considering some of the literature that has analysed the development of corporate governance norms in a variety of jurisdictions.
