Marriage to end, Baden-Clay told mistress Accused wife-killer Gerard Baden-Clay told his mistress he would one day end his marriage and pursue an "unconditional relationship" with her, a court has heard. Mistress Toni McHugh told the Brisbane Magistrates Court on Monday the pair had the conversation in December 2011, four months before Allison Baden-Clay disappeared. Baden-Clay is facing a committal hearing over charges he murdered Allison and interfered with her body, which was found on the banks of a Brisbane creek 10 days after she vanished last April. The crown is alleging the affair was a motivating factor in the murder. Ms McHugh said Baden-Clay had broken off their affair in September 2011, but arranged a meeting in December to tell her his marriage was "short-term." "The conversation was around him coming to give me some indication he didn't plan to be in the marriage indefinitely," she said. He told me that he was one day going to come to me unconditionally. She was questioned closely by defence barrister Peter Davis SC about the sexual contact the pair had between December 2011 and April 2012, saying they met up on a couple of occasions. "I loved him," she said, adding they last met up for coffee around three weeks before Allison's disappearance. Earlier on Monday, Ms McHugh told the court Baden-Clay had told her to "lay low" while police investigated his wife's disappearance. But he later advised her to tell the truth about their relationship. She said Baden-Clay had broken off their affair seven months earlier, but that she believed they were back together when Allison disappeared.
