The 53-year-old won the huge sum with a £1 lucky dip ticket bought in his local shop in Kilcreggan, near Helensburgh. Bill has worked on Abe Hamilton's Knockderry Farm for more than 30 years and although he did enjoy a few days off, it was back to work as usual on Wednesday, feeding and looking after the beef cattle and 300-head Blackface flock on the 1400-acre farm.
"We will need to take some time to think about what we do now," said Bill when The Scottish Farmer caught up with him on the farm. "I'll work on until Christmas and take it from there. We have never owned our own house, so my wife Allison would like to buy a new house in Balloch where she was brought up, but we won't rush into anything.
"I bought everyone in my local pub a drink, but other than that we haven't started to spend it. I'm not used to so much attention, I've had people stopping me on the road to shake my hand."
