Yes, that's the one.
In Serbian language, there is a difference between term of "party" - there are two terms, to be more precise "stranka" and "partija".

In this wiki case on English there is a problem because I think there is no other term for political party than party.
The one made in 1989. is made by Serbian conservative royalists, and the second one is made by Serbian republicans which strongly support concept of Serbian citizenship, not national state.

This in wiki is also true: this oppositional leader (he is within a parliamentary party) somewhat supports Kosovo's independence. People for the most time mark him as someone who is suspicious for his source of money, and there are claims that he is maybe financed by Albanians, but I STRONGLY doubt that.

I am also sure that there are parties on Kosovo that are suggesting that it would be wise to stay with Serbia, no?
