“Rav Moshe Shternbuch shlita is a descendant of the GRA by the way.”
Rav Moshe Shternbuch is the Ravaad of the Badatz of the Eidah HaChareidus. I don’t think that he’s chasidish himself but he surely strongly affiliates with the strictest chasidic denominations in Eretz Yisroel including Satmar whose first two Rebbes were the Nasi of the Eidah and the Divrei Yoel was the Gaavad of Yerushalyaim as well. I also think Rav Moshe may have headed a part of Satmar in England where Rav Moshe’s son is currently in place.
