Since Estonian readers know already, this summary is only for English speakers: after many years of haunting the political landscape with gradually growing vote counts, the Estonian Conservative People's Party (authoritarian right), has finally collapsed into a crisis.
It's not a crisis of values (they are all still conservative and many are authoritarian too), but a crisis of internal democracy due to the dictatorial habits of the "ruling family" - father and son Mart and Martin Helme.
Three prominent members, one of whom intending to challenge the party leader in internal elections, were kicked out during a board meeting, after which several more prominent members (among them several MPs and one MEP) either left the party of announced intention of leaving.
Everyone involved had adequate warning about the lack of internal democracy, it is just that they tolerated it longer than anticipated. The big bang comes after years of gradual kick-outs.
