Prince Jaime, Duke of Noto

Jaime's grandfather the Infante Don Carlos, Duke of Calabria, had to consider whether the future marriage of Prince Pedro to Sofía Landaluce y Melgarejo would meet the conditions established in the Sovereign Act, signed in Naples, 7 April 1829, Law no. 2362, which gave the "head of Our House of Bourbon... such authority as is necessary to protect the purity and splendour of the throne", by requiring all members of the dynasty to have formal permission to marry.

This was confirmed in the Sovereign Act.

signed at Naples, 12 March 1836.

Law no. 3331.

The marriages of all members of the dynasty that had been considered capable of transmitting dynastic rights had been to royal princesses until the marriage of Prince Ranieri to Countess Carolina Zamoyska in 1929.

The ultimate decision of the Infante Carlos to permit his son's marriage to be considered a dynastic marriage followed the marriages of the daughters of King Juan Carlos without them being required to renounce their right of succession to the Spanish throne, and a change in the marriage rules of the House of Austria.

His paternal grandparents are Infante Carlos, Duke of Calabria (1938–2015) and his wife, Princess Anne of Orléans.

The Duke of Noto was educated at the Centro Universitario Villanueva (with a degree in law), and then obtained a master's degree in management from the IE University Business School.

Prince Jaime of Bourbon-Two Sicilies, Duke of Noto (born 26 June 1992) is a Spanish aristocrat and heir to the headship of House of Bourbon-Two Sicilies as eldest son of Prince Pedro, Duke of Calabria.

Jaime was born on 26 June 1992 in Madrid, Spain as the illegitimate son of then Prince Pedro, Duke of Calabria (born 16 October 1968) and Sofia Landaluce y Melgarejo (born 23 November 1973).

He was later legitimized by his parents' marriage, following which he was joined by six siblings: three brothers and three sisters.

The Infante Carlo and his wife attended the marriage of Prince Pedro on 30 March 2001 and the marriage is treated as a dynastic marriage transmitting full right of succession to all the children of Prince Pedro and his wife.

It was made clear by the date of the marriage of the future King Felipe VI in 2004 that the children of Prince Pedro and his wife had full dynastic rights and the children of the Duke and Duchess of Noto (titled Duke and Duchess of Calabria since 2015) bear the style of Royal Highness and the title of Prince(ss) of Bourbon-Two Sicilies.

On 25 September 2021 at Monreale Cathedral in Palermo Jaime married Lady Charlotte Lindesay-Bethune, youngest daughter of James Lindesay-Bethune, 16th Earl of Lindsay and his wife, Diana Mary Chamberlayne-Macdonald.

On 13 October 2023, the Duke and Duchess of Noto had their first child in London: a daughter named Francesca Sofía.

From September 2018 to January 2022 he was a director of the Plug and Play Tech Center in Paris and from July 2019 also in Spain.

Then after serving as a director at Heritage Holdings (January 2022–June 2023) he joined Aquiline Capital Partners, London, in July 2023.
