Prince Friso, left in a coma following a skiing accident nearly 18 months ago, has been brought back to the Netherlands, the state information service RVD confirmed on Tuesday.

Friso, second son of former queen Beatrix, was being treated at the Wellington Hospital in London. He arrived at the Huis ten Bosch palace on Tuesday, where he and his family will spend the summer, the RVD said.

The prince’s condition remains unchanged and he continues to display ‘minimal consciousness’, the RVD said. Further treatment in hospital is no longer necessary and options are now being looked at for a permanent place of care in either the Netherlands or Britain.

Friso married Mabel Wisse Smit in 2004. The couple have two daughters.
