If he did, its never been made public. He seems to have been happily married.

Winston Churchill constantly wrote to his wife Clementine whenever they were apart. In one of this letters to her, he wrote:

"My darling Clemmie, in your letter from Madras you wrote some words very dear to me, about having enriched your life. I cannot tell you what pleasure this gave me, because I always feel so overwhelmingly in your debt, if there can be accounts in love…What it has been to me to live all these years in your heart and companionship no phrases can convey."
