The Lord President of the Council is the presiding officer of the Privy Council of the United Kingdom and the fourth of the Great Officers of State, ranking below the Lord High Treasurer but above the Lord Keeper of the Privy Seal. The Lord President usually attends and is responsible for chairing the meetings of the Privy Council, presenting business for the approval of the Sovereign. In the modern era, the incumbent is by convention always a member of one of the houses of Parliament, and the office is normally a Cabinet position.
