The location where the ticket was purchased has now been revealed.

Shane Cantillon runs the local store with the help of his brother Mark, his father Greg and an additional 30 local staff members.
Cantillon spoke about how delighted he was to have sold the ticket.
He said: "My phone lit up last night and to my surprise, the National Lottery number came up. I was aware the winning Lotto ticket was won in Cork so I knew it could only be one thing – I must have sold the winning ticket.
"Anybody working in the retail trade will tell you that selling a winning lottery ticket to one of your own customers is the next best thing to winning it yourself."
A National Lottery spokesperson said: "We are still waiting to hear from the lucky winner of the €10.7 million jackpot, so we are appealing for all players to check their tickets carefully and if you are the big winner, please sign the back of the ticket and contact our prize claims team on 1800 666 222 or email claims@lottery.ie, and we will make arrangements for you to claim your prize."
