His Majesty's Attorney General for England and Wales is the chief legal adviser to the sovereign and Government in affairs pertaining to England and Wales as well as the highest ranking amongst the law officers of the Crown. The attorney general is the leader of the Attorney General's Office and currently attends the Cabinet. Unlike in other countries employing the common law legal system, the attorney general does not govern the administration of justice; that function is carried out by the secretary of state for justice and lord chancellor. The incumbent is also concurrently advocate general for Northern Ireland.

The Law Officers are the senior legal advisors to His Majesty's Government of the United Kingdom and devolved governments of Northern Ireland, Scotland and Wales. They are variously referred to as the Attorney General, Solicitor General, Lord Advocate, or Advocate General depending on seniority and geography - though other terms are also in use, such as the Counsel General for Wales. Law Officers in these roles are distinguished by being political appointees, while also being bound by the duties of independence, justice and confidentiality among the other typical professional commitments of lawyers. These roles do not have any direct oversight of prosecutions nor do they directly lead or influence criminal investigations. This is a distinguishing factor between Law Officers and the State Attorneys General of the United States or US Attorney General.
