Campbell made the claims in an interview with Dagens Nyheter which follow his revelations in September that Sweden is one of America's key partners in efforts to monitor internet communications across the globe.
"When you put together the pieces of the puzzle it becomes clear that Sweden worked together with the U.S and the UK in order to create new laws for mass surveillance online," Campbell told the newspaper.
He added, "Sweden's new laws in 2008 coincided with the so-called Fisa Amendment Act in the U.S. which we now know was used to open the entire American part of the internet for surveillance. In Britain they proposed similar laws but were stopped."
In 2008 the FRA law was passed which allows The Swedish National Defence Radio Establishment (FRA) to wiretap telephone and internet traffic which crosses Swedish borders. The bill has been in use since January 1st 2009 and was introduced as anti-terrorism legislation.
According to Campbell the law means Sweden passes on information to the U.S and he stated that the country is as vital a partner to America as Israel is.
"When it comes to the amount of intelligence that Britain and the United States received from other countries globally then Sweden is at the same level as Israel."
"Sweden controls cables through the Baltic sea while Israel has access to them in the eastern Mediterranean," he said.
Campbell added that he garnered the information from documents he read from whistle blower Edward Snowden and has promised further revelations based on these records.
