Two daughters who were shockingly made pregnant 18 times over a 25-year period by their father have received an apology from the agencies who failed to protect them.

The apology came at a press conference that revealed the findings of a serious case review.

The Sheffield man was given a life sentence after admitting 25 counts of rape in 2008. He cannot be named.

The review found missed opportunities and collective failures to protect the children over three decades.

It was carried out by Safeguarding Children Boards in Sheffield and Lincolnshire and acknowledged the family had contact with 28 different agencies and 100 members of staff over 35 years.

Sue Fiennes, independent chair of Sheffield Safeguarding Children Board, said: "We want to apologise to the family at the heart of this case. It will be clear that we have failed this family."

Chris Cook, independent chair of Lincolnshire Safeguarding Children Board, said: "We are genuinely sorry. We should have protected you."

The review showed the family moved 67 times so the father could avoid detection.
