Queen Sonja of Norway, 87, has been admitted to an hospital after ‘breathing difficulties’, the royal palace announced.

‘The Queen was transported by medical helicopter from the royal chalet in Sikkilsdalen, where the royal couple were spending the Easter holidays,’ a statement read.

It is understood that the family has spent most of the holidays at the chalet this time of year, according to the NTB news agency.

Queen Sonja was briefly hospitalised in January after experiencing cardiac fibrillation, a rapid and irregular heartbeat. She then had a pacemaker installed, a procedure the palace described as ‘successful.’

FEMAIL has reached out to the palace for comment.

The queen is married to King Harald – Europe’s oldest reigning monarch at 87 – who has also had a pacemaker inserted last March after contracting an infection during a private vacation in Malaysia.

Both Sonja and Harald appeared to be in good spirits earlier this month, as they welcomed the President of Iceland for a gala dinner at the Royal Palace in Oslo.

The couple hosted Halla Tómasdóttir, 56 and her husband Björn Skúlason, 51, at an opulent evening with their Scandinavian neighbours.
