Mr Ashman, who currently works as a loss prevention officer at TK Maxx as well as studying for a criminology degree at the University of Worcester, has said he would like to buy a car with his National Lottery winnings.
The rest of his winnings will go towards setting up his own property development business.
He said: “It’s my birthday in a couple of weeks.
“It’s then my dad’s 50th and my three brothers have special birthdays too, so we’ll wait until after June 21 to get together with lots of family and friends and have a fantastic party.”
Mr Ashman is the second National Lottery scratch card winner from the Black Country in the last month, with carer Bee Murton from Bilston winning £300,000 at the end of April.
