Sian Jones, a childhood friend of Gareth Williams, has told the inquest into his death she did not believe he was a transvestite, despite the extensive amount of women's clothing in his flat.
She said: "I feel like he would have been able to confide in me... and I would not have judged him."
Ms Jones said she would see Mr Williams every couple of days and he would shower her with gifts.
She told the inquest: "He did say he was not happy in London. He said that he found it quite lonely in London and within work it was very cliquey."
