"We've decided to take a break. It was a mutual decision," Pernald, a 29-year-old employee at an advertising agency, told the Expressen newspaper.
Sources told the publication Princess Victoria's recent betrothal to gym owner Daniel Westling had a lot to do with her 29-year-old brother's split with his girlfriend.
"Suddenly, everything got serious. Earlier, Emma and Carl Philip could manage to get along in the relationship. It was half spent, but it worked," a source told Expressen. "With Daniel's and Victoria's engagement, Carl Philip and Emma came back into focus. Now they were expected to take the plunge."
The Local said Pernald has refused to discuss the reason for the break-up.
"I'm not going to comment as to why or on other details," she told Expressen.
