Katrina Yates was heartbroken when she discovered that her daughter Nicola had embarked on an affair with Katrina's ex-husband and Nicola's biological father after tracing him in secret almost eight years ago.
Nicola and her father Andrew Butler spent years living together as boyfriend and girlfriend and have been to court twice charged with having sex with an adult relative after Katrina reported their inappropriate relationship.
Last year Andrew was finally jailed, but after her mother wrote a pleading letter to the judge Nicola was given a suspended sentence and her and her family started the painful process of trying to rebuild their relationship.

Nicola moved in with her younger sister Natalie and things were going well.
But in January this year Andrew was released and Nicola suddenly disappeared, cancelling her phone number, deleting her Facebook contacts and cutting off all contact with her family.
Today Katrina and her younger daughter Natalie appeared on This Morning to discuss Nicola's betrayal and why they fear that she has gone on the run with her father again.
Katrina, whose ex-husband Andrew left the family when daughter Nicola was just four years old said:
'Nicola wasn't interested in her father growing up.
'She was 20 when she started looking for him, when she embarked on a journey to find him.
'I advised her that I didn't think it was a very good idea, told her some things that had happened and thought it had stopped.
'I thought that was the end of it.'

what was happening.
told Phillip Schofield and Holly Willoughby: 'I saw a picture and
thought it must be someone that just looks like him, then Natalie (her
other daughter) went back and found a letter in his name.
'I couldn't believe it, I was devastated, I could see the evidence but I wouldn't believe that it was real.
WHAT IS Genetic Sexual Attraction
Research by the British Medical Journal showed that half of those separated from relatives at a young age experience strong sexual feelings when they are reunited.
Psychiatrists believe the natural repulsion brothers and sisters feel for one another as children acts as an inhibitor to committing incest.
But those who miss out on this time can develop powerful, obsessive feelings for their sibling in adulthood.
Genetic Sexual Attraction (GSA) is a term that describes the phenomenon of sexual attraction between close relatives, such as siblings, first and second cousins or a parent and offspring who first meet as adults.
It is not the same as incest, though this is what it is called if a sexual relationship is then entered into.
The term GSA was coined 30 years ago by American Barbara Gonyo. She wrote a book about the lust she felt for the adult son she had given up for adoption 26 years earlier. She never acted on her feelings.
GSA is rare between people raised together in early childhood due to a reverse sexual imprinting known as the Westermarck effect, which desensitizes them sexual attraction.
Experts believe that this effect evolved to prevent inbreeding.
I first confronted her she denied it. Then she got angry and accused me
of interfering in her life. then she admitted it and said that he was
my ex it was nothing to do with me and she could do what she wanted.
'I understand that she didn't ever know him, but he was there when she was born.'
After Andrew was jailed Nicola moved in with her younger sister Natalie.
Natalie said: 'We started to build a bond again, getting our nails done and things but there was always something there, it wasn't right.'
In January this year Andrew was released and Nicola disappeared, her family haven't seen either of them since.
Katrina said: 'I believe that they are back together.
'[If she is watching now] I don't have anything to say. I think that is it now
'We went though such a horrific time. It has been devastating for the whole family, including her grandparents.
'Natalie was attacked in a car park when she was 5 months pregnant and nearly lost the baby.
'If she has chosen to make a life with him there's nothing we can do about it.'
At the time of second court hearing in July last year Natalie said: 'I got in touch with him in the beginning because I wanted a proper father/daughter relationship. I hadn't seen him since I was very little.
'I don't really know how or why it happened, why things developed the way they did.
'I can honestly say I will never see him ever, ever again. I don't want to have anything to do with him ever again.'
