Hakatan, i don’t know about their website, but the london beis din has normal rabbis. Rav gelley is a yekkishe rov, another is on the beis din of bais havaad in Lakewood… they’re not mizrachisten.
In kashrus, KLBD has a similar reputation to the OU in America. There are definitely modern people among the UK rabbinate, but if rav jakobovitz, who himself was quite respected in halacha, and the beis din had a heter… I’m not going to fight it. I do believe that r..mirvis would be required to distinguish himself as a non participant, as per what rav jakobovitz wrote.
