Analysis
The quip aligns with Churchill’s known humor and self-deprecating yet grandiose style, and it was first attributed to him in **Roy Jenkins’ 2001 biography** (*Churchill*), citing a 1911 dinner conversation. However, no contemporaneous account (e.g., letters, diaries, or Violet Asquith’s own writings) confirms the *precise* wording or setting. Asquith’s memoirs and Churchill’s published correspondence omit the remark, leaving its exact phrasing unverifiable. The anecdote is widely repeated but lacks direct primary evidence.
Background
Winston Churchill and Violet Asquith (daughter of Prime Minister H.H. Asquith) shared a close, flirtatious friendship in the 1910s, exchanging witty banter documented in their letters. Churchill’s reputation for colorful metaphors and self-mythologizing makes the remark plausible, but his most reliable quotations stem from speeches or published works—not private conversations. The glow-worm analogy fits his tendency to blend humility with ambition (e.g., his 'bulldog' or 'lion' self-comparisons).
Verdict summary
Churchill likely made a *similar* witty remark about being a 'glow-worm' in 1911, but the exact phrasing and context with Violet Asquith are unverified by primary sources.
