For those who don't want to read the whole sentencing report here's a paragraph about the children.
The children were facilitated by the care and stability provided following their removal in June 2019. However difficult it must have been for all concerned, a married couple accepted the invitation of the social work department to offer respite for the four children who feature in this case. Care then continued. The new carers’ actions were as kind, caring, generous and selfless as it is possible to imagine that anyone’s could be. From the desperate darkness of their earlier life, their new carers brought sunlight into blighted young lives, offering hope, a home, structure and nurture over a period of years. They continue to care for some of the children.
