Prince Daniel, Duke of Västergötland (born Olof Daniel Westling on 15 September 1973), is the husband of Crown Princess Victoria of Sweden. Prior to his marriage to the heir apparent, Daniel was a personal trainer and gym owner and ran a company called Balance Training with three gyms in central Stockholm. His full name is Olof Daniel Westling Bernadotte as registered with the Swedish Tax Authority’s national census.

Daniel was born to Olle and Ewa Westling (born Ewa Westring) in Örebro, on the day Carl XVI Gustaf ascended the throne. His family lived in the Brickebacken area, and he grew up in Ockelbo. He has a sister, Anna Westling Söderström (formerly Anna Westling Blom, born Anna Westling). He was christened at Almby Church in January 1974. His family has Forest Finnish ancestry and his father is a leader in the Forest Finnish community.

After completing his education, he briefly served, as part of national conscription, in the Swedish Army at Hälsinge regemente in Gävle. In 2001, he met the Crown Princess when he became her personal trainer.

On 1 July 2008, he moved into a one-bedroom rental apartment in the Pagebyggnaden building on the grounds of Drottningholm Palace. The move was confirmed by the Royal Court.

On 24 February 2009, Westling and the Crown Princess received official permission to become engaged from King Carl XVI Gustaf and the Government of Sweden.[10] Such permission is necessary according to the terms of the Swedish Act of Succession.

Westling suffered from a congenital (but not hereditary) ailment causing impaired renal function. Three months after his engagement, on 28 May 2009, Westling underwent a kidney transplant at Karolinska University Hospital. His father was the donor. The operation was a success. Victoria could not be present when the operation took place because she was in Greenland at the time.

The wedding took place in Stockholm Cathedral on 19 June 2010, the 34th anniversary of her parents’ wedding. After the wedding, the Duke and Duchess of Västergötland moved into the Haga Palace.

On 17 August 2011, the Swedish royal court announced that Prince Daniel and Crown Princess Victoria were expecting their first child in March 2012. She gave birth to a girl on 23 February 2012, Princess Estelle, Duchess of Östergötland. Daniel took his paternity leave and switched parental roles with Victoria when Estelle began preschool.

On 4 September 2015 the court announced that the couple were expecting their second child, due to be born in March 2016. On 2 March 2016, Victoria gave birth to a boy, Prince Oscar, Duke of Skåne.

In November 2009 it was reported that Daniel Westling was to step down as CEO and member of the Board of Directors of the Balance company. He will still be an equity partner. It was expected that the same procedure would be followed with his involvements in other companies, before he became prince. His business positions: Balance – CEO and member of the Board of Directors (stepped down November 2009); Master Training – CEO and member of the Board of Directors; Brasil Development – member of the Board of Directors

Daniel has been attending events with Crown Princess Victoria and representing the royal family since his marriage. On 21 August 2010, he undertook his first engagement with the rest of the royal family to celebrate 200 years of the House of Bernadotte being on the throne. On 26 September 2010, Daniel went on his first tour with Victoria, visiting France in connection with the Bernadotte anniversary. Daniel also attends the Nobel ceremony and banquets.

The Swedish Royal Court announced that Westling would become “Prince Daniel” and “Duke of Västergötland”, corresponding in form to the style used by previous Swedish princes, including Victoria’s younger brother Prince Carl Philip, Duke of Värmland, i.e. Prince + Given name + Duke of [Place].

As was further announced in May 2010, on his wedding day Westling was made a prince of Sweden and was granted the style Royal Highness, making him an official member of the Swedish Royal Family and on a par with other senior members of the Royal Family, such as Prince Carl Philip, Princess Madeleine and Princess Lilian. At Stockholm Cathedral, he was also then made a knight of the Royal Order of the Seraphim and already wore its badge and ribbon upon emerging after the ceremony
