Jonathan Caplan

Biography

High-profile British barrister (King's Counsel) who says he has followed the subject for fifty years and who in June 2026 published 'Not For Disclosure' (Century / Penguin Random House), a Sunday Times bestseller. The book applies his trade of weighing evidence to a compilation of testimony from scientists, intelligence officials, politicians and military insiders, and includes material on Truman-era meetings, the alleged 'Majestic 12' group and allegations linking JFK to the subject. In September 2026 he told Sky News's Wilfred Frost there is 'no question' about visitation and that the U.S. Congress 'has been misled for 80 years'. He enters the corpus as a disclosure voice with professional credibility in the British sphere, with two caveats: his work is a compilation of others' testimony, not primary evidence, and it relies on the 'Majestic 12' documents, which serious research considers fraudulent.
