Sweden's Princess Madeleine has given birth to a daughter in New York City, the country's Royal Palace has said.
Their daughter, born late yesterday, is a first child for her and her American husband, banker Christopher O'Neill.
Royal spokesman Svante Lindqvist said both mother and baby, whose name was not disclosed, "are in good health".
The younger sister of Crown Princess Victoria, Madeleine is fourth in line to the Swedish throne.
Sweden has a constitutional monarchy in which the royals primarily serve as figureheads. The king is the country's head of state, but his powers are limited to ceremonial duties.
