An Irish brother and sister who unwittingly fell in love and had a child together plan to flout the law and marry later this month.
The couple, aged in their 20s and living in Leinster, first spoke to the Irish Mail in May when they discovered through DNA tests that they shared a father.
Now they have told the newspaper they plan to marry and spend the rest of their lives together, even though they will be breaking the law by doing so.
The couple, who met in a nightclub, blame the legal system for failing to inform the man about his real identity after his biological father was denied access to him.
"The way I see it, if the system can know about things and hide the facts, then I can do the same they turned a blind eye and so can we," the man, going by the pseudonym James, told the Mail.
"People can criticise and say it is not right but they should say the same about what was done to me in the family law courts."
The couple were originally planning a Christmas wedding but decided to do it sooner and said it will be very small.
They plan to go on a honeymoon several weeks after the wedding.
