"[W]hen he was born, legally he was my brother. Just as legally, he was my mother's son."

For in a case that has divided opinion across Britain and led to questions about the robustness of our fertility laws, the married mother-of-three is not only Miles’s grandmother, but also the woman who gave birth to him.

On face value, it’s a story to make anyone recoil. But Anne-Marie simply carried the child. Using a donor egg fertilised by Kyle’s sperm, she became the first woman in the UK to be a surrogate for her own son.

The arrangement emerged only last week when a High Court judge ruled that Kyle could now adopt Miles. The paperwork arrived on Saturday, meaning that although Kyle was classed as both the baby’s father and brother when he was born, that is no longer the case. Today he is simply the baby’s father.

Kyle says: ‘I’ve never thought of him as my brother. None of us have. But when he was born, legally he was my brother. Just as legally, he was my mother’s son.
