Harry Platt (Joshua Leavy) is struggling after his mother Sarah Platt's (Tina O'Brien) imprisonment for the murder of Theo Silverton. The Platt family was shocked when Sarah confessed to the crime, and her absence has left Harry in the care of his sister Bethany Platt (Lucy Fallon) and her ex-boyfriend Kit Green (Jacob Roberts). Kit, despite his recent breakup with Sarah, agreed to stay at the flat to provide stability, but his efforts have hit a rough patch. This week, his decision to send Harry to Little Big Shotz sparked uproar, leaving viewers wondering about Harry's biological father.
Who Is Harry Platt’s Biological Father?
Harry is the son of Sarah Platt and Callum Logan (Sean Ward). Callum appeared in 114 episodes between 2014 and 2015 as Kylie Platt’s drug-dealing ex-boyfriend and the biological father of Max Turner. He was determined to gain custody of Max by any means, and his plan included starting a romantic relationship with Sarah, during which she became pregnant with Harry. The relationship ended when Max discovered a gun in Callum’s flat, prompting Sarah to break things off.
What Happened to Callum Logan?
Callum was killed off in the 2015 live episode of Coronation Street. During a confrontation, Kylie hit him over the head with a wrench to save Sarah, who was being attacked by Callum. Kylie and David Platt then hid his body beneath Gail Platt’s annex. The body was discovered eight months later when Tyrone Dobbs (Alan Halsall) crashed his truck into the annex, causing structural damage. Six months after Callum’s death, Sarah gave birth to Harry.
Sarah’s Reflections on Callum
Callum is rarely mentioned on the show these days, but Sarah did open up about Harry’s parentage to Dee-Dee Bailey in 2024. Dee-Dee, who was facing her own pregnancy decision after falling pregnant by abuser Joel Deering, confided in Sarah that she feared seeing Joel every time she looked at her baby. Sarah explained that she barely thought about Callum because she was so focused on how much she loved her son.
As Sarah’s prison nightmare continues, Harry’s immediate future remains uncertain, with Kit stepping in as a father figure and Bethany taking on primary care. The ongoing storyline highlights the lasting impact of Callum’s actions on the Platt family, even years after his death.
