STOCKHOLM (Reuters Life!) - Sweden's Princess Madeleine, third in line to the throne, has become engaged to her long-time boyfriend, the Swedish royal court announced on Tuesday.

Madeleine, 27, the youngest of the king's three children, plans to marry 30-year-old Jonas Bergstrom, a lawyer. The two have been together for seven years.

The wedding date has not been decided.

Madeleine's elder sister, Crown Princess Victoria, who is first in line to the throne, announced in February plans to marry her commoner boyfriend, personal trainer and gym owner Daniel Westling next year.

Sweden is a constitutional monarchy and the king has no political power.

Sweden's monarchy traces its origins back more than 1,000 years, though the current royal family assumed the throne in the early 19th century, when French marshal Jean-Baptiste Bernadotte became king. He had been elected as successor to the Swedish throne by Sweden's parliament in 1810.

Carl XVI Gustaf has been King of Sweden since 1973. The last Swedish royal wedding was in 1976 when he married German-born Silvia Sommerlath, whom he met at the Munich Olympics in 1972.
