As a loyal wife and mother Eileen Paisley has been a constant, albeit low-profile presence at the right hand side of her fire-brand preacher husband for almost 60 years.
However, in an interview to be screened tonight Baroness Paisley gives an insight into just how powerful an influence she has been throughout her husband's career both in politics and in the Free Presbyterian Church.
While Mr Paisley speaks candidly about his departure from the party he founded under pressure from his predecessor Peter Robinson, it is his wife, formerly known as Eileen Cassells, who pulls no punches when it comes to venting her anger.
While she entered into electoral politics before her husband, elected as a councillor for east Belfast in 1967 prior to the formation of the DUP, Baroness Paisley would later take a back seat to allow her husband centre stage.
The interview with journalist Eamonn Mallie reveals just how powerful Mrs Paisley was when it came to shaping her husband's thinking, not just as a wife but as a trusted political adviser.
The mother of five reveals that during political negotiations, she and her husband talked over every aspect of what it would mean for the party, her family and Northern Ireland if Ian Paisley did an about turn and went into government with Sinn Fein. She also shows just how protective she is of her husband and children.
When asked about sleaze allegations levelled at her son Ian Paisley jnr she refers to the sex scandal when Iris Robinson was discovered having an affair with a teenager.
"Ian's name was cleared by the authorities in Stormont, everything that was said against him was proved to be false and he never brought any sleaze. His wife didn't do anything wrong, he didn't do anything wrong.
"There was nothing morally wrong with his character or his life. And we know eventually where the sleaze did come from.
"It came in the home of the man who is now leader himself, Peter Robinson, it came from his family, not from the Paisley family."
