The 38-year-old digital entrepreneur announced his departure from the Pirate Party via his Facebook page. Weyer played a significant role as one of the co-founders of the party back in 2009.
Weyer served as Vice President for several years and, until recently, held the position of Coordinator for the Centre district.
In the most recent elections, Weyer finished sixth on the Pirate Party's list in the Centre constituency. While the reasons behind his decision to leave the party are said to have been communicated internally, Weyer has chosen not to publicly disclose them.
