Three children fathered by a man with "unhealthy" attitudes to sexual relationships have been placed for adoption on the orders of a High Court judge.
Mrs Justice Pauffley said the man - who lived with the children's mother - posed a risk of "significant physical harm" to children and adults.
The judge said she made care orders after concluding that the children's mother was "unable to make any kind of break" from their father.
She said two boys were placed for adoption in March when aged 19 months and six months and a girl was placed for adoption in December when aged 10 weeks.
Mrs Justice Pauffley said no-one involved could be identified.
Detail has emerged in a written ruling published by the judge following private hearings in the Family Division of the High Court in London.
"(The father) poses a risk of significant physical harm to any child or adult with whom he resides," said Mrs Justice Pauffley, in the ruling, which has been published on a legal website.
"(The mother) is unable to identify and thereafter respond appropriately to the risk of harm."
She added: "(The father) holds unhealthy and or u nwholesome attitudes to sexual relationships."
And she went on: "(The mother) was unable to make any kind of break between herself (and the father)."
Mrs Justice Pauffley said she realised that orders she had made meant permanent separation between children and natural parents and were the "most serious kind of state intervention".
And the judge said on a "human level" she had sympathy with the couple.
"Neither of them had the kind of start in life which anyone would want for a child," she added. "They never had the foundation which might have enabled them to provide adequately for any of their three children."
Mrs Justice Pauffley said she made care orders following applications from local authority social workers.
