Christine Cole, from Leigh Park, bought her winning 10X Cash ticket in the shop she owns, Super Shop newsagents in Emsworth.
The 57-year-old is still taken aback by winning the huge prize.
Christine said: “I’ve never had money like this in my life, I don’t know what i’m going to even spend it on yet.”
Posing for pictures with her husband Peter, she said: “I’m absolutely delighted, I’m over the moon.”
Christine had to be investigated by lottery officials before being awarded her jackpot to make sure she purchased the scratchcard.
