It was Karen Jones who was invited to speak at the House of Lords.
Karen Jones was described by a judge as a serious danger to the public after killing Michael Cutler by strangulation and suffocation and leaving his body to decompose in a sheet in the kitchen of their home. Karen Jones was 18 at the time and living as a man. Karen Jones was apparently provoked into killing the man during an argument.
Karen Jones was released in 2002, and five days after being released from prison Karen Jones attacked and attempted to rape a woman working as a shop assistant who was working in a shop selling women's underwear and accessories to men. Karen Jones was 21 at the time and now living as a woman (however a woman lives 
)
Karen Jones forced a lemon into the woman's mouth, punched the woman in the face, held the woman by her hair, and attempted to rape the woman.
The rape was unsuccessful because Karen Jones was unable to get aroused enough to penetrate the woman.
The woman described the violent attack and attempted rape as being so terrifying she believed Karen Jones would kill her.
This violence and attempted rape was all apparently so Karen Jones could go back to prison as a cry for help to get a sex change operation.
The attack and attempted rape took place as Karen Jones was housed in a women's bail hostel.
The judge at this trial said that Karen Jones was an extreme risk to the public to the point that this risk might result with someone else's death.
They were added to the sex offenders register, but I'm unclear if that was under the name Karen Jones or Mark Jones.
Karen Jones has apparently changed names twice to prevent people finding out about their past.
