“ although you do not have to return a verdict in respect of the assault charge, you are entitled to consider the evidence about that from both X and the defendant in determining where the truth lies in relation to the count of sexual assault that you are trying and your view of where the truth lies about that [i.e. the assault charge] may assist you in coming to a conclusion about the sexual assault. The prosecution say, as you know, that the sexual assault was part and parcel of his violent, obsessive behaviour arising out of his belief that she had been sexually unfaithful to him during the hen night in Cardiff. The defendant says that although his behaviour was appalling, he did not sexually assault X.”
