The man, a business consultant, was concerned that two of his three children – who are all under 13 – might be at risk of abduction because of the family's connections.
Telling the school that the children were related to European royalty and that his brother was a senior Army officer, the father is said to have asked for permission – which was granted – to pick up his children inside the two schools attended by his eldest children.
However, one of the head teachers went to the police because of her "concerns".
This led to the parents' background being investigated and concerns being raised, initially over the father's mental state and then for the safety of his children.
Lord Monckton, who has investigated the allegations, described the episode as "the worst case of child abduction by social services that I have ever come across".
