Karen Danczuk's brother has been jailed for 15 years for a series of sex assaults on her and two other victims.
Michael Burke (38), the brother of the estranged wife of Rochdale MP Simon Danczuk, shook his head and threw up his hands yesterday as he was sentenced following a trial last month at Manchester Crown Court.
His sister later waived her right to anonymity as a victim of sexual offences to brand her brother a "monster" who had "robbed me of my childhood" and made her suicidal.
During the three-week trial the mother-of-two told the court her brother abused her at the family home in Middleton, near Rochdale, from the age of six or seven - progressing to rape when she was aged 11 - until she was in her mid-teens.
Burke denied 15 counts of rape, one attempted rape and one indecent assault against his sister and two other women, spanning an 18-year period from 1992 to 2010.
But the jury found him guilty of eight counts of rape and another serious sexual offence against the three women, including three counts of rape against his sister, when she was aged between nine and 11 and he between 14 and 16.
He was cleared of nine other serious sexual offences. The two other women have not waived their right to anonymity and cannot be identified.
Mrs Danczuk told the jury the abuse had ruined her schooling, left her incapable of love and intimacy and that she struggles with depression and anxiety.
Judge Andrew Gilbart said: "She was your little sister, over whom you held sway... you groomed her. Your little sister was susceptible to anything you suggested. You have shown not a shred of remorse."
Burke was given an extended five years on licence when he is released from jail after serving his sentence, and was put on the Sex Offenders' Register for life.
