Official Opposition Shadow Cabinet
The Official Opposition Shadow Cabinet (usually known simply as the Shadow Cabinet) is, in British parliamentary practice, senior members of Her Majesty's Loyal Opposition who scrutinise their corresponding Government ministers, develop alternative policies, and hold the Government to account for its actions and responses. Since May 2010, the Labour Party has been Her Majesty's Loyal Opposition, and its leadership therefore forms the current Shadow Cabinet.
Not all Opposition frontbenchers are members of the Shadow Cabinet, which is composed of the most senior Opposition Members (usually around twenty).
The Leader of the Opposition, the Opposition Chief Whip and Opposition Deputy Chief Whip are the only Members of the Official Opposition to draw remuneration for their Opposition roles in addition to their salaries as Members of Parliament. The Leader of the Opposition and the Opposition Chief Whip in the House of Lords also receive a salary.
