Liam was put on the judging panel for the Hotten Retail Awards and David Metcalfe tried sucking up to Liam, desperate to win the award. Maya and Liam had marital problems and Maya instigated an affair with David. Liam found out and declared he wanted to divorce Maya. Liam developed a hatred for David and took pleasure in telling him that his estranged wife Tracy Metcalfe had aborted their baby - infuriating Tracy who threatened to report him for breaking patient confidentiality.
Liam decided to sell their house, throwing Maya onto the street as the house was in Liam's name. Liam moved in temporarily with a friend until their house was ready, which Liam's daughter Leanna was not happy about. He began an affair with beautician Bernice Blackstock. Liam encouraged Bernice to break up with her boyfriend Daz Spencer so they could stop sneaking around, but Bernice was reluctant to as Daz relied on her and she didn't want to hurt his feelings.
