United Kingdom company law regulates corporations formed under the Companies Act 2006. Also governed by the Insolvency Act 1986, the UK Corporate Governance Code, European Union Directives and court cases, the company is the primary legal vehicle to organise and run business. Tracing their modern history to the late Industrial Revolution, public companies now employ more people and generate more of wealth in the United Kingdom economy than any other form of organisation. The United Kingdom was the first country to draft modern corporation statutes, where through a simple registration procedure any investors could incorporate, limit liability to their commercial creditors in the event of business insolvency, and where management was delegated to a centralised board of directors. An influential model within Europe, the Commonwealth and as an international standard setter, UK law has always given people broad freedom to design the internal company rules, so long as the mandatory minimum rights of investors under its legislation are complied with.
Company law, or corporate law, can be broken down into two main fields. Corporate governance in the UK mediates the rights and duties among shareholders, employees, creditors and directors. Since the board of directors habitually possesses the power to manage the business under a company constitution, a central theme is what mechanisms exist to ensure directors' accountability. UK law is "shareholder friendly" in that shareholders, to the exclusion of employees, typically exercise sole voting rights in the general meeting. The general meeting holds a series of minimum rights to change the company constitution, issue resolutions and remove members of the board. In turn, directors owe a set of duties to their companies. Directors must carry out their responsibilities with competence, in good faith and undivided loyalty to the enterprise. If the mechanisms of voting do not prove enough, particularly for minority shareholders, directors' duties and other member rights may be vindicated in court. Of central importance in public and listed companies is the securities market, typified by the . Through the Takeover Code the UK strongly protects the right of shareholders to be treated equally and freely trade their shares.
