A primary school teacher and a barrister who specialises in children's cases 'routinely neglected' their adopted sons, with the teacher strangling and racially abusing one of the boys, a judge has found.

The High Court heard how the couple's two youngest children, aged 10 and 15, were subject to multiple instances of abuse.

The teacher, X, called the 15-year-old, who is of mixed ethnic heritage, a 'black b*****d', the judge found.

On one occasion in January last year, X 'strangled the teenager', and on another, forced one of the older siblings to 'eat soap' for using inappropriate language.

X also subjected the two children to emotional abuse by swearing at them and using threatening language.
