Accused of sexual assault by two women he'd had relationships with.
One occurred about two years ago, and is still being investigated by New Zealand police. The other is coming from a woman he had a relationship with twenty years ago.
Gaiman claims the woman making the more recent claims might be suffering from some form of false memory syndrome. Most of the articles mention that there is testimony and text messages from her friends supporting her story. They weren't there, so I would guess they are testifying about things she told them at the time. I'm not sure that would be admissible in court (hearsay?). Perhaps they could testify about her emotional state at the time. Legally, that might have some relevance.
He also denies the older accusation and points out that she seems to have regret over their relationship. That sounds to me like he believes she's upset that he ended the relationship, and the accusation could be some sort of revenge.
Of course, the first priority should be making sure the survivors get all the support they need.
Politically, Gaiman is pretty far to the left. He aligns with the crowd that believes that women simply do not make false accusations about such things. I don't have any direct quotes from him on the subject, though, don't know what he's said about similar cases in the past. His current stance is that women might lie in certain ultra rare instances (like his), anyway.

Daily Mail: Tortoise reported that she sent Mr Gaiman numerous text and video messages in which she explicitly said she had consented during their sexual encounters, and also said she loved him and was grateful to him.
The woman told the podcast: 'At the end of it he made me feel like it was consensual, but it wasn't consensual.' She added: 'He sort of lured me if you will into his psychological labyrinth. So it was not straightforward at all.'
