Linda Gilroy, 62, represented Plymouth Sutton, in Devon, from 1997 until 2010.
She married Gilroy’s father Benny, now 72, in 1987 – nine years after he was divorced from his first wife Grace, 76, in 1978.
Benny Gilroy worked part-time as his MP wife’s parliamentary and constituency assistant and the couple shared a harbour-side flat in Plymouth.
She eventually lost her seat to the Tories.
The couple travelled to Edinburgh for the trial, and regularly accompanied Gilroy to hearings. When passers-by challenged Gilroy’s wife Andrea about why she was loyal to her husband, the former MP was heard to say: “Because he’s not guilty.”
