David made life hell for his mother Gail over a number of years.He was upset when his father was going to leave Weatherfield with new girlfriend Robyn in 2005 and refused to speak with him, but eventually made up with Martin before he departed for Liverpool.David originally believed his sister Sarah to be the reason for the break-up, as she had recently given birth at the age of thirteen, which had put a strain on the family.
David is the son of Martin Platt and Gail Tilsley, born on Christmas Day 1990 and weighed 8lb.
In March, Phil was under suspicion by Gail, and during dinner, Phil tried to protest his innocence, but in rage threw David across the table.
Gail ordered Phil out of the house for hitting David.
He was the result of an unplanned pregnancy after Gail had a relationship with his much younger father.
Gail actually planned on having David aborted, but Martin stopped her from making the decision as he convinced her he was ready to be a father. However in 2000, they divorced after Martin had an affair with Rebecca Hopkins, a nurse at Weatherfield General where they both worked.
