Former DUP leader Sir Jeffrey Donaldson has been found guilty of 18 historical sex offences against two women when they were children.
A jury at Newry Crown Court convicted him of one count of rape, 13 counts of indecent assault and four counts of gross indecency.
His wife Eleanor Donaldson has been found to have aided and abetted his crimes following a trial of the facts.
Jeffrey Donaldson, 63, was told he will be sentenced at the same court on September 25 and was remanded in custody.
He showed no reaction to the verdicts as he stood with his hands folded in front of him.
He had pleaded not guilty to the offences, which spanned a period between 1985 and 2008.
Complainants A and B both gave evidence at the trial, alleging they were abused as children.
Jeffrey Donaldson spent two days giving evidence during the trial, where he repeatedly denied the allegations.
Eleanor Donaldson, 60, from Dublinhill Road, Dromore, Co Down, denied several charges of aiding and abetting her husband.
She faced a trial of the facts on mental health grounds, which tested the evidence but could not result in a criminal conviction.
