Halfway up the countdown is the only character in the poll that viewers have witnessed their birth. Born on Christmas Day 1990 to Martin Platt and Gail Tilsley, David didn’t have a major role in the soap for more than a decade, when Jack P Shepherd started playing the role. He became a main character after his parents split up and his mum married psycho Richard Hillman – which has mentally affected him. Over the years he has developed from an innocent schoolboy to a lying, scheming and manipulating sociopath. Among his evil deeds are writing greeting cards under the name Richard to his family members, pushing his mother down the stairs, nearly killing niece Bethany, ruining sister Sarah’s marriage to Jason Grimshaw, going on a vandalising rampage on the street and framing neighbour Gary Windass for burglary. For an 18 year old, he’s got a long list of enemies – including his sister! A relationship with Tina McIntyre failed to distract him from mischief, and she ended the relationship when she realised David wasn’t normal.
