The High Court in England has ruled that children under 16 - who say they want to change gender - are unlikely to be able to give their informed consent to treatment with drugs that block puberty.

The case was brought by a young woman who regretted her decision to have treatment and argued that a court order should be needed for children to take the medication.

Transgender campaigners have criticised the decision and the only NHS clinic to offer the treatment to children says it will appeal against the ruling.
