Pictures have been released of the Instrument of Consent, an elaborate notice of approval, in which the Queen agrees that Prince Harry can marry Meghan Markle.

As one of the first six people in line to the throne, Harry had to obtain permission from the Sovereign to be wed under the Succession to the Crown Act 2013.

Harry was fifth in line to the throne when he got engaged, but is now sixth due to the birth of Prince Louis.

The document, which is transcribed in calligraphy, and issued under the Great Seal of the Realm, was signed by the Queen in March.

It states: 'Now know ye that we have consented and do by these presents signify our consent to the contracting of matrimony between our most dearly beloved grandson Prince Henry Charles Albert David of Wales KCVO and Rachel Meghan Markle.'

The wording is different from that of the instrument signed to give consent to the marriage of the Duke and Duchess of Cambridge in 2011, when Kate was described as 'our trusty and well-beloved' Catherine.

Meghan Markle first met the Queen for afternoon tea at Bucking Palace in October 2017.

Although the monarch was unlikely to have withheld her blessing, she would only have said 'no' on the advice of the Prime Minister.

If Harry failed to get the Queen's approval, he and his future descendants would have been disqualified from succeeding to the Crown.
