Ms Thorning-Schmidt was so concerned about the issue that she questioned Milo – who refers to himself as ‘non-binary transmasculine’ and uses male pronouns – to the point where he became ‘annoyed’.
‘But that’s fair – my role in life is to test if Milo was completely sure about his decision,’ she added.
However, she clarified that she realised that being non-binary was ‘quite a cool place to be’ because ‘you don’t have to pick a side’.
It was revealed in The Mail on Sunday last year that Milo had undergone breast removal surgery after coming out as ‘non-binary’ – meaning that a person identifies as neither female nor male.
In the three-part podcast series entitled ‘Han/Ham/Milo’ (He/Him/Milo), which was broadcast in Danish, Milo said that before the mastectomy his Labour MP father Stephen Kinnock travelled to Denmark to be with him.
According to Milo’s sister Johanna, their father cooked a ‘delicious’ curry the evening before the surgery and the family watched a Harry Potter film.
Describing the moment they picked up Milo – who was still ‘foggy’ – from hospital after being operated on, Ms Thorning-Schmidt said: ‘It was quite a special experience and we were relieved it was over. You are always a bit worried when someone is undergoing surgery.’
