Having branded the allegation that he had raped the woman as "ridiculous", the amateur boxer was captured on an officer's bodyworn camera claiming they had had consensual sex.

In the footage, played to jurors at Canterbury Crown Court, the 39-year-old could also be heard saying: "I'm good-looking and, not out of pity or anything, this girl was nice, cool, but not good-looking.

"She was a nice girl, so I thought I would do her a favour. That's my mentality. In the morning, I thought she would appreciate that.

"The next thing I'm being called a rapist. That is ridiculous. I would never pick her to f*** her."

The court heard that several months before the rape, Manning had stopped taking his medication for bipolar disorder and was drinking and taking drugs to excess.

But while it was said by a psychiatrist that the defendant was likely to have been in a "clinical relapse stage of hypomania" at the time - a condition exacerbated by his substance misuse and resulting in a heightened sex drive - the judge rejected any notion that his mental health provided mitigation for his offending.

Furthermore, he said his "ugly words" uttered on arrest demonstrated the "lack of empathy and respect" common among those who commit rape.

The court heard the woman had fallen asleep after a house party at which she had been drinking and smoking cannabis but woke to find herself being molested from behind by Manning - who she had only met that evening - before he went on to rape her.

Giving evidence at his trial in May this year, she told the jury: "I woke up to someone touching me - it hurt. I didn't know what to do. I just froze."

When asked why she had not struggled, the woman added: "Because he told us he was a boxer, and he's a lot stronger than me. He could have hurt me."

Once her ordeal was over, she waited until Manning, of Caxton Road, Margate, fell asleep before alerting a friend and then police.

Manning claimed in court that he and the victim had been flirting during the evening and, although he admitted he was never given verbal confirmation of her wanting to have sex, he insisted what occurred was consensual.

But the jury saw through his lies and unanimously convicted him of rape and sexual assault.

Having returned for sentencing on Friday, Manning learnt of the "profound" impact his vile conduct had had.

In a victim personal statement read to the court by prosecutor Paul Valder, the woman described how the memories of the attack are "too frightening to cope with" and her life is "frozen in trauma".

"Before this happened to me, I would have described myself as a normal young lady....I would describe myself as happy-go-lucky and doing the normal things a young lady would do," she wrote.

"This has all changed now and my life is consumed by multiple thoughts of fear, anger and hatred towards him.

"This on a daily basis leads me on a self-destruct pathway. I often have thoughts of ending my life and I admit I drink excessively to blank those thoughts out and get through the day the best I can."

Explaining how she had been diagnosed with PTSD and suffers from panic attacks and anxiety, she continued: "My whole life seems to have come to a standstill.

"I feel I have literally frozen in trauma and I can't see a way out. He has taken everything away from me.

"I'm trapped with this fear and will carry this with me for the rest of my life."

Kieran Brand, defending, told the hearing his client was "a different Clinton Manning" when medicated and argued that the victim, having been awake when the more serious offence took place, was not "particularly vulnerable" in the legal sense.

Jailing Manning for six years, Recorder David Jeremy KC said the woman not only "froze" but that Manning had "wiped her with a cloth" once he had finished "in the hope, thinking she was still asleep, that she would never know what had been done to her".

Referring to her impact statement, he added: "She describes the profound change your crimes have produced. Her life is consumed by fear and anger."

In respect of the sex offender's mental state, the judge told Manning he would have been "very well aware" of the consequences of failing to comply with his medication and consuming drugs and alcohol - choices which were voluntary.

And of his account given to police on arrest, Recorder Jeremy said: "While your bipolar may have resulted in a sense of disinhibition, the underlying thoughts behind those ugly words were yours and you demonstrated the lack of empathy and respect often possessed by someone who commits the crime of rape."

Manning's family, who sat in the public gallery, called out "We love you, Clint" and "We love you, son" as he was led to the court cells.

They also thanked the judge as he left the courtroom.
