Variant using 洩れず, an alternative kanji for 漏れる. Less common but still seen.

Etymology

From ご (honorific prefix) + 多分 (たぶん, 'many cases, majority') + に (particle) + 漏れず (negative continuative of 漏れる 'to leak out, be omitted'). Literally 'without leaking out from the many cases', i.e., 'not being an exception to the common pattern'. The phrase is a fixed idiomatic expression.
