Crown Prince Haakon Steps Up as Regent as King Harald V's Health Deteriorates in Oslo Hospital
Crown Prince Haakon has been appointed regent of Norway after his father, King Harald V, developed a bacterial blood infection that worsened his condition while he was being treated at the Rikshospitalet in Oslo.
The Norwegian Royal House issued an official update on 23 August 2026, stating the 89-year-old king's health had deteriorated over the weekend and that he was receiving antibiotics for the infection. Doctors said King Harald had responded well to the treatment and that his condition was stable Royal Central. Reuters describes King Harald as Europe's oldest current head of state Reuters.
The king's hospitalisation began on 17 August 2026 — his second admission this year — after a reaction to treatment for a form of anaemia. He was placed on sick leave for two weeks, and the Royal House announced that Crown Prince Haakon, 52, would serve as regent in the interim, meaning he would carry out the monarch's constitutional duties while his father was unable to do so People. Haakon was seen driving to the Rikshospitalet on the Monday morning following the latest deterioration to be at his father's side.
The sequence of complications was rapid. After the initial admission for anaemia, King Harald was given cortisone, which led to fluid retention. Six days later, doctors identified the bacterial blood infection that caused his health to worsen. All of the king's forthcoming engagements have been put on hold.
Prime Minister Jonas Gahr Støre said the news about the king's health was affecting the whole country. King Harald has ruled Norway since January 1991, making 2026 the 35th year of his reign.
The regency falls to Haakon at a bruising moment for the Norwegian royal family. Crown Princess Mette-Marit, Haakon's wife, is recovering after undergoing a lung transplant as her pulmonary fibrosis — a scarring of the lung tissue — worsened. The couple were set to celebrate 25 years of marriage on 25 August, with no public festivities planned. Mette-Marit also came under scrutiny earlier in the year when documents revealed links between her and convicted sex offender Jeffrey Epstein. Her son from a previous relationship, Marius Borg Høiby, was sentenced to four years in prison after being convicted of offences including two counts of rape.
None of those matters touches the regency itself, which is a constitutional arrangement set in train by the king's sick leave. But they frame the moment Haakon steps forward. The instrument is straightforward: the Council of State, the formal body through which the Norwegian monarch acts on government business, can vest the crown's functions in an heir when the sovereign is incapacitated. The paperwork names the regent. The rest is carried out in his name.
The official press releases from the Royal House were published in the "For pressen" section of its website at kongehuset.no Kongehuset.no. What remains is the waiting — for the antibiotics to finish their work, and for the next bulletin from the palace.
