Censorship in Sweden?

What a lucky coincidence att Swedish and Norwegian are so alike. I did not have to translate.
It is about the book that I've just finished reading. Still being under impression.
When I now see that some Swedish politician tries to censor the book, I understand why.

There are ties between the social democrats in Sweden and certain secret deals within the intelligence community during the 90s. I dont know if I'm allowed to write it here but it's not only about the Estonia catastrophe. There are things as well...

Strange thing is why the social democrats try to act and censor the truth now? Why now?
I hope mister Thomas Hartman can provide answer to that.
