[19th March 1937]

Whereas Your Majesty, by Your Majesty’s Royal Message to both Houses of Parliament, has been pleased to recommend that provision should be made for a Regency in certain events:
Act amended by Regency Act 1953 (2 & 3 Eliz. 2 c. 1), s. 2
And whereas Your Majesty in the same Message put both Houses of Parliament in mind of the difficulties which arose in relation to the exercise of the Royal Authority at the time of the illness of His late Majesty King George the Fifth in the year nineteen hundred and twenty-eight and of His last illness in the month of January nineteen hundred and thirty-six, and recommended that Parliament should consider whether it be not expedient to make permanent provision for the purpose of securing the exercise of the Royal Authority as well in the event of the incapacity of the Sovereign as in the event of the minority of the Sovereign on His Accession and in certain other circumstances:

1 Regency while the Sovereign is under eighteen.
(1) If the Sovereign is, at His Accession, under the age of eighteen years, then, until He attains that age, the royal functions shall be performed in the name and on behalf of the Sovereign by a Regent.
(2) For the purpose of any enactment requiring any oath or declaration to be taken, made, or subscribed, by the Sovereign on or after His Accession, the date on which the Sovereign attains the age of eighteen years shall be deemed to be the date of His Accession.

2 Regency during total incapacity of the Sovereign.
(1) If the following persons or any three or more of them, that is to say, the wife or husband of the Sovereign, the Lord Chancellor, the Speaker of the House of Commons, the Lord Chief Justice of England, and the Master of the Rolls, declare in writing that they are satisfied by evidence which shall include the evidence of physicians that the Sovereign is by reason of infirmity of mind or body incapable for the time being of performing the royal functions or that they are satisfied by evidence that the Sovereign is for some definite cause not available for the performance of those functions, then, until it is declared in like manner that His Majesty has so far recovered His health as to warrant His resumption of the royal functions or has become available for the performance thereof, as the case may be, those functions shall be performed in the name and on behalf of the Sovereign by a Regent.
(2) A declaration under this section shall be made to the Privy Council and communicated to the Governments of His Majesty’s Dominions ....

3 The Regent.
(1) If a Regency becomes necessary under this Act, the Regent shall be that person who, excluding any persons disqualified under this section, is next in the line of succession to the Crown.
(2) A person shall be disqualified from becoming or being Regent, if he is not a British subject of full age and domiciled in some part of the United Kingdom, or is a person who would, under section two of the Act of Settlement, be incapable of inheriting, possessing, and enjoying the Crown , or is a person disqualified from succeeding to the Crown by virtue of section 3(3) of the Succession to the Crown Act 2013; and section three of the Act of Settlement shall apply in the case of a Regent as it applies in the case of a Sovereign.

(4) If the Regent dies or becomes disqualified under this section, that person shall become Regent in his stead who would have become Regent if the events necessitating the Regency had occurred immediately after the death or disqualification.
