Speaking on LTV's interview show One On One, the spymaster said there were "various socially active people who are trying to influence public opinion against the preservation of Latvian sovereignty."
Unsurprisingly, he declined to name and names and also refused to clarify whether he was talking about politicians or people in other walks of life.
"Latvian politicians are very varied," said Maizitis.
At the same time, he noted that "I do not think that Latvia, as a NATO member faces a military threat."
However, political decisions and actions in relations with Russia could be interpreted in various different ways, he said, letting very little of real substance escape during the hour long head to head.
Maizitis' interview took place as SAB published its 8-page annual report which said: "The most active in working against the interests of Latvia are the Russian secret services. Their influence and authority in Russia is high and in some areas continues increase, thereby increasing the hazard they present to Latvia."
The report also made a point of drawing attention to Kremlin efforts to open a local Sputnik propaganda newswire channel in Latvia - just hours before Latvia's internet registry closed down the site in question.
