Counsellor of State

In the United Kingdom, Counsellors of State are senior members of the British royal family to whom the Monarch, presently Elizabeth II, delegates certain state functions and powers when she is abroad or unavailable for other reasons (such as short-term incapacity or sickness). Any two Counsellors of State may attend Privy Council meetings, sign state documents or receive the credentials of new ambassadors to the United Kingdom.

History

The first Counsellors of State were created in 1911 by an order in council of George V, and this process was repeated on each occasion of the King's absence or incapacity. The Regency Act 1937 established in law those individuals that could serve as Counsellors of State. The Counsellors of State are the consort of the monarch and the first four people in the line of succession who meet the qualifications. These qualifications are the same as those for a regent: they must be at least 21 years old (unless s/he is the heir-apparent or presumptive, in which case the requirement is 18 years), they must be domiciled in the United Kingdom, and they must be a British citizen. One exception was made for The Queen Mother (see below).

Since the passage of the Regency Act 1937, the only person to have been a Counsellor of State while not a royal is The Earl of Harewood (although Princess Maud of Fife styled herself simply Lady Southesk); prior to that the Lord Chancellor, the Lord President of the Council, the Prime Minister and the Archbishop of Canterbury had been appointed to the position by George V.

Present

Currently, the Counsellors of State are:

  1. HRH The Prince of Wales
  2. HRH Prince William of Wales
  3. HRH Prince Henry of Wales
  4. HRH The Duke of York

List of Counsellors of State

The following is a list of all the people who have served as a Counsellor of State, since the passage of the Regency Act 1937, in chronological order. Prior to this, Counsellors were only appointed for specific trips and the appointment lapsed on the King's return. Note that this list contains the dates not of when they ruled, but when they actually held the position.

Flag of Canada Canada
Flag of the United States United States
  1. HRH The Duke of Gloucester
  2. HRH The Duke of Kent
  3. HRH The Princess Royal
  4. HRH Princess Arthur of Connaught

Absences: The Queen accompanied the King on his trip. Notes: Since the Queen accompanied the King, she was technically not on the Council. However, she was listed among those in the Council. This created a problem, and was solved by the Regency Act 1943, which modified the Regency Act 1937, and said that if someone is absent and does not act as Counsellor, they will not be listed among the Counsellors. This occasion was the first rule of the Council of State under the provisions of the Regency Act 1937.

1943
North Africa tour
  1. HRH The Duke of Gloucester
  2. HRH The Princess Royal
  3. HRH Princess Arthur of Connaught
  4. HH Princess Maud, Countess of Southesk (styled as Lady Southesk)

Notes: HRH The Princess Elizabeth, the heiress-presumptive, was soon to turn 18. She would have been allowed to reign in her own right or act as a regent to her father on her 18th birthday; however, she could not act in the Council of State until she was 21. This was also fixed by the Regency Act 1943. This was Lady Southesk's only time as a Counsellor.

1944
Flag of Italy Italy
  1. HRH The Princess Elizabeth
  2. HRH The Duke of Gloucester
  3. HRH The Princess Royal
  4. HRH Princess Arthur of Connaught

Notes: Though at this time, Viscount Lascelles should have been a Counsellor of State, he was a prisoner of war. The regular solution would be for him to simply be not included among the Counsellors. Nevertheless, Princess Arthur was made a replacement. This was Elizabeth II's first time helping to rule the country.

1947
Tour of Africa
  1. HRH The Duke of Gloucester
  2. HRH The Princess Royal
  3. Viscount Lascelles

Absences within Council: HM The Queen and HRH The Princess Elizabeth were with the King.
Notes: Lord Harewood's first time as a Counsellor of State.

1951
King's illness
  1. HRH The Princess Elizabeth, Duchess of Edinburgh
  2. HRH The Princess Margaret
  3. HRH The Duke of Gloucester
  4. HRH The Princess Royal

Notes: The King had planned to take a cruise with the Queen and Princess Margaret while Princess Elizabeth was on tour; however, this would have only left the Duke of Gloucester and the Princess Royal as Counsellors of State. There were plans to change the law so as to allow someone further down the succession to act as Counsellor of State, but the King died before the issue came up and the Regency Act 1953 did not make this rule.

The immediate Royal Family (the Queen, the Duke of Edinburgh, and all four of their children) were all present for part of the games – the first time that they had all been together in one place outside the British Isles. Thus, the Duke, the Prince of Wales, and Princess Anne were unable to act as Counsellors during their respective absences of July. However, the Queen Mother, Princess Margaret, and the Duke of Gloucester were all available for the duration of the tour.
