I want to know the answer to the following question:
What party was Helsinki-86 in disagreement with?
All the background I'm provided with is that "The CTAG (Latvian: Cilvēktiesību aizstāvības grupa, Human Rights Defense Group) Helsinki-86 was founded in July 1986 in the Latvian port town of Liepāja by three workers: Linards Grantiņš, Raimonds Bitenieks, and Mārtiņš Bariss.". Is that enough to answer the question?
Answer: no
