Dr Matt Carter is a fictional character from the British ITV soap opera Coronation Street, played by Oliver Mellor.
Matt overhears Natasha and Gail McIntyre (Helen Worth), who is Nick's mother and the medical centre's receptionist, arguing.
He hears Natasha accuse Gail of hacking into her medical records and she admits it, insisting Nick should be told the truth, thereby breaking the rule of patient confidentiality.
Whilst Matt is having a drink in The Rovers, an explosion occurs at the Joinery Bar, causing a tram to crash on to the street.
Matt takes charge of the casualties and tends the wounded, treating many residents, including Sunita Alahan (Shobna Gulati).
He offers Claire Peacock (Julia Haworth) mental health advice after she discovers that her husband Ashley (Steven Arnold) has died in the accident.
They invite him around to Number 7 after claiming one of them is ill. Sunita and her husband Dev Alahan (Jimmi Harkishin) return and are shocked and embarrassed by her aunts' behaviour.
Matt begins dating Tina McIntyre (Michelle Keegan), much to the annoyance of Tommy Duckworth (Chris Fountain), who becomes jealous of him.
He later tends to Kylie Platt (Paula Lane) when she fakes illness so her sister, Becky McDonald (Katherine Kelly) can access his computer to print off Tracy Barlow's (Kate Ford) medical records.
Eileen Grimshaw (Sue Cleaver) enlists the help of Matt, along with several other male residents, to perform in a charity strip routine at the Bistro.
Matt later discusses Paul Kershaw's (Tony Hirst) state of mind with Eileen when he goes to book a taxi at StreetCars.
The character was introduced in August 2010 as Dr Carter, Gail McIntyre (Helen Worth)'s new boss at the medical centre.
Speaking to the Daily Mirror, Mellor explained: "When Chris and I are in character, we're like rutting stags trying to be the alpha male.
