A father and daughter who admitted conspiracy to commit incest have lost a bid to have their convictions overturned.
The Court of Appeal was told that Mr Y and Ms A formed a sexual attraction to one another in late 2008 and agreed to have sex and perform "other sexual acts''.
They had not seen each other for many years and had only recently resumed contact via a social networking website.
They were convicted of conspiracy to commit incest and ordered to come up for sentencing within 12 months if called upon by the court.
Mr Y and Ms A appealed, saying they should have been discharged without conviction claiming that the judge did not properly consider the impact of a conviction on their careers and failed to take into account Ms A's immigration status and child custody issues.
