**The claim:** Nigel Farage's father, Guy Justus Oscar Farage, was still stockbroking at age 75. **Key findings:** 1. **Identity and profession confirmed:** Multiple sources — BBC News, Wikipedia, Yahoo News UK — confirm that Guy Justus Oscar Farage was a stockbroker who worked in the City of London. He returned to the trading floor at the Stock Exchange Tower on Threadneedle Street in the mid-1970s after overcoming alcoholism. 2. **Age calculation:** According to FamilySearch genealogical records and Companies House records, Guy Farage was born in November 1935. The interview took place on 2 December 2011, at which point he would have been 76 (having turned 76 the previous month). "At the age of 75" would correspond to roughly November 2010–November 2011, consistent with the interview timeframe. 3. **Business activity into his 70s:** Companies House records show Guy Farage was appointed as a member of COEPTUS 2008 LLP on 15 April 2008, when he would have been approximately 72–73 years old. This confirms continued business engagement well into his 70s, consistent with — though not specifically proving — stockbroking at 75. 4. **No contradictory evidence:** No source suggests Guy Farage had retired earlier than age 75. All available evidence is consistent with continued professional activity into his mid-70s. Nigel Farage's statement that his father "has just retired" from stockbroking at 75 is not contradicted by any public source. **Assessment:** The core assertion — that Guy Farage was still stockbroking at age 75 — is consistent with all available evidence. His profession as a stockbroker is well-documented, Companies House records confirm business activity into his 70s, and no source contradicts the specific timing. However, no public source independently confirms the precise detail that he was specifically stockbroking (as opposed to other business activity) at exactly age 75. This is a biographical detail about a private individual's retirement timing, where the son's own statement in an interview is the most direct account available. The available evidence strongly supports the claim without independently confirming the exact detail.
