Abstract
The aim of this study was to examine the impact of corporate governance on the performance of financial institutions in the United Kingdom. The sample size consists of FTSE 350 financial institutions listed on London Stock Exchange from 2016 to 2020. It specifically investigates the relationship between organisation performance as measured by Return on Assets (ROA), Return on Equity (ROE) and Net Profit and corporate governance mechanisms such as board size, ratio of independent non-executive directors, gender diversity, audit committee, and board duality, using panel regression analysis. The finding from the research shows that board size, ratio of independent non-executive directors and gender diversity has a negative relationship with organisation performance, while audit committee independence and board duality have a positive relationship with organisation performance.
