Sarah Sugden has grown up on Emmerdale. Once known chiefly for the serious illnesses she faced as a child, she is now at the centre of a story about parenthood, a family betrayal and the death of Dr Caitlin Todd.
The short answer: Katie Hill plays Sarah Sugden. She is the daughter of Debbie Dingle and Andy Sugden, and she and her husband Jacob Sugden are raising baby Leyla Sugden. They have since learned that Leyla Sugden is not their biological daughter. Sarah Sugden is also responsible for the push that caused Dr Caitlin Todd’s fatal fall, while her grandmother Charity Dingle has taken responsibility for the death.
Who plays Sarah Sugden?
Katie Hill has played the character since 2017. Sarah Sugden first appeared in 2005 and was portrayed by younger performers before Katie Hill took over the role.
That long screen history is important. Viewers have seen Sarah Sugden move from childhood stories into adult decisions about marriage and raising a child. Katie Hill’s character is still part of the programme as of this update; there has been no confirmed announcement that she is leaving.
How is Sarah Sugden related to the Dingles and Sugdens?
Sarah Sugden’s mother is Debbie Dingle, previously played by Charley Webb. Her father is Andy Sugden, previously played by Kelvin Fletcher. On the Dingle side, Charity Dingle and Cain Dingle are her grandparents. On the Sugden side, Robert Sugden is her uncle through Andy Sugden’s adoptive family.
Her name can cause confusion because Emmerdale has had two characters called Sarah Sugden. The older Sarah Sugden was Andy Sugden’s adoptive mother. Debbie Dingle and Andy Sugden’s daughter was named in her memory.
Those connections explain why the current story reaches across two of the soap’s best-known families. The dispute with Charity Dingle is not just a disagreement between relatives: it has tested where Sarah Sugden feels she belongs and whom she can trust.
What happened to Sarah Sugden’s health?
Illness shaped much of her childhood. Sarah Sugden was diagnosed with Fanconi anaemia and later experienced leukaemia, throat cancer and heart failure. She received a heart transplant.
In 2025, a fertility appointment led to a cervical cancer diagnosis. Complications during subsequent surgery resulted in an emergency hysterectomy. The storyline changed how Sarah Sugden could pursue her hope of having a child, and it led her family to explore surrogacy.
These are events in a fictional character’s story, not details about Katie Hill’s health. They also help explain the urgency behind Sarah Sugden’s wish to build a family, without reducing every decision she makes to her medical history.
Who are baby Leyla Sugden’s parents?
Sarah Sugden married Jacob Gallagher, played by Joe-Warren Plant. He began using the name Jacob Sugden. The couple hoped to have a child, and Charity Dingle, played by Emma Atkins, agreed to carry a baby for them.
That plan did not unfold as Sarah Sugden and Jacob Sugden believed. Charity Dingle became pregnant after sleeping with Ross Barton. She gave birth to Leyla Sugden in April 2026 and concealed the baby’s biological parentage, allowing the couple to believe the surrogacy plan had worked.
Leyla Sugden is biologically the daughter of Charity Dingle and Ross Barton. Sarah Sugden and Jacob Sugden have been raising her. That distinction does not erase their bond with the child, but the deception denied them the chance to understand the circumstances from the beginning.
The discovery was particularly painful for Sarah Sugden because Charity Dingle had offered to help after her cancer surgery. What appeared to be an act of support became a secret about the child she was raising. It also put pressure on her marriage: Jacob Sugden had to absorb the truth about Leyla Sugden alongside another devastating confession.
What happened with Dr Caitlin Todd?
Dr Caitlin Todd had blackmailed and sexually assaulted Charity Dingle. During a confrontation in August 2026, Sarah Sugden pushed the surgeon, who struck her head on a coffee table and died.
Charity Dingle took responsibility in an attempt to protect her granddaughter. Serena Sugden, Sarah Sugden’s cousin and a former police officer, became involved in the aftermath. Sarah Sugden later changed her account more than once, complicating the investigation and increasing the danger to everyone involved.
The facts of the on-screen incident should not be flattened into a simple claim that Sarah Sugden planned a murder. The push caused a fatal injury; the resulting statements, attempted cover-up and potential legal consequences are separate parts of the story.
Where does the story stand now?
By 2 October, Sarah Sugden knew that Detective Sergeant Thea Ramsden and Serena Sugden had been working together in an effort to reduce the consequences for Charity Dingle. Sarah Sugden said she was prepared to tell the police what really happened, even though doing so could expose her own role in Dr Caitlin Todd’s death.
The episode released on ITVX on 5 October 2026 adds another complication involving Detective Sergeant Thea Ramsden and a recording from Charity Dingle’s police interview. That development is described in Radio Times’ report on the episode. It does not establish a final outcome for Charity Dingle’s case or Sarah Sugden’s future.
For now, Sarah Sugden faces two questions at once: how to be honest about Dr Caitlin Todd’s death, and how to move forward with Jacob Sugden and Leyla Sugden after the truth about the baby.
