THE Archbishop of Canterbury has made a sensational discovery that is real father was Sir Winston Churchill’s right hand man.
Rev Justin Welby was left completely stunned to learn his biological father is the late Sir Anthony Montague Browne and not Gavin Welby.
His mother Lady Williams of Elvel, 86, revealed she bedded Sir Winston’s private secretary in a night "fuelled by a large amount of alcohol on both sides".
In a statement, she added: "It appears that the precautions taken at the time didn't work and my wonderful son was conceived as a result of this liaison.
"Although, as has already been made public, Gavin Welby and I had a short and, sadly, dysfunctional marriage, neither of us ever doubted that we were the parents of our son Justin.”
Baffled by the news, the Archbishop said: “In the last month I have discovered that my biological father is not Gavin Welby but, in fact, the late Sir Anthony Montague Browne.
"This comes as a complete surprise."
He added: "This revelation has, of course, been a surprise, but in my life and in our marriage Caroline and I have had far worse.
"I know that I find who I am in Jesus Christ, not in genetics, and my identity in him never changes."
Mr Welby said his mother Jane Williams and Gavin Welby were both alcoholics, adding that his mother has been in recovery since 1968, and has not touched alcohol for over 48 years.
Gavin Welby died "as a result of the alcohol and smoking" in 1977, when the Archbishop was 21.
Lady Williams, who split from Gavin Welby in 1958, married Baron Williams of Elvel in 1975.
She said that after getting married, she did not see Sir Anthony again for a long time.
She said: “After Gavin and I broke up in 1958 Anthony and I met occasionally but although he may have asked how Justin was, there was nothing that gave me any hint that he might have thought he was Justin's father.”
The Archbishop said his childhood was “very messy” because of the couple’s alcohol addiction.
He said: "As a result of my parents' addictions my early life was messy, although I had the blessing and gift of a wonderful education, and was cared for deeply by my grandmother, my mother once she was in recovery, and my father [Gavin Welby] as far as he was able."
