Children killed by parents after court-ordered access
At least four children have been killed in the last five years by a parent with a known history of violence, after a family court ordered they have access to their child, this programme has found.
And dozens of parents have revealed their abusive ex-partners were granted unsupervised contact with their child.
More than 125 MPs have signed an open letter calling for an urgent inquiry.
The Ministry of Justice said a child's welfare was always the priority.
"Where there is evidence of domestic abuse, the courts are bound by law to consider potential harm to the child and this overrides any presumption of parental involvement," a spokesperson said.
