A Spanish soldier today asked a judge to jail his Welsh ex-wife for breaching a court order to return two of their five children to Spain.
Tomas Palacin Cambra, 53, argued that teacher Jennifer Jones, 47, was in contempt of court and should be committed to prison.
Ms Jones, who comes from Llanelli, Carmarthenshire, denies contempt. She says the children, aged 16 and 14, refuse to return to live with their father in Spain and she says it has "proved impossible" to make them return.
Judge Sir James Munby is due to make a decision after hearing argument at a hearing in the Family Division of the High Court in London.
The two children have been at the centre of an international tug-of-love dispute for more than a year.
The case first hit the headlines in October 2012 after a High Court judge raised the alarm when Ms Jones disappeared.
Sir James, president of the Family Division of the High Court, has heard how a Spanish court had made orders saying the children had to live with their father and three siblings in Spain following the break-down of the couple's marriage.
