“The British voters have spoken and that's the way it is,” the PM told broadcaster NRK early on Friday.
Solberg said she is now worried about the wider political consequences of the United Kingdom's vote to withdraw from the EU.
“I think this will create a more introverted Europe, which will be concerned with finding solutions to organizational problems instead of providing solutions to the issues voters really want addressed. How do we secure enough growth? How do we create jobs?”
The final result of Thursday's EU referendum shows that 51.9 percent of British voters backed Brexit.
“This should be a warning for the leaders of the EU and national leaders of the European countries, that giving young people hope for the future by ensuring job creation is among the most important things we do,” Solberg said.
Britain's opting out of the EU will have no consequences for Norway's EEA Agreement, Solberg said.
“We have a good EEA agreement with the EU. So it depends on what Britain's agreement with the EU will be, and how it will impact Norway. Our relationship with the EU remains unchanged, and in the short term our relationship with the United Kingdom is also in tact,” she said.
“We need to work on prioritizing how Norwegian interests are best served by the EU moving forward, and the question is how to find political solutions,” Solberg added.
