A retired volunteer teacher thought he had won a pint of milk when he had in fact scooped £1m on a scratchcard.

Bill Bett said he could not believe it when he scratched of the card to read 1MIL.

The 69-year-old told his three sisters, who believed he was "winding them up", and has pledged to use the money to look after his family.

Mr Bett, who used to teach art to children with learning difficulties, has bought a bungalow with the prize money.

He said the new home will enable him to paint again as the stairs in his former home had become a struggle due to health issues.

The Monopoly Millionaire scratchcard winner, from Markinch in Fife, said: "I always used to say no one wins £1m on a scratchcard.

"When I saw the amount it didn't really click at first. On the card it reads 1MIL and I thought what does this mean - I've won a pint of milk?

"I went back into the shop and asked them to check it. They confirmed that I had won and that I'd have to call the lottery line. I couldn't believe it but I actually remained quite calm."

He added: "When I got home I phoned my three sisters who all thought I was winding them up. But they said it couldn't have happened to a better brother and are so happy for me.

"I tucked the scratchcard carefully behind the cover of my tablet for safe keeping. I was still double-checking it right up until it was validated a week later."

He had purchased the winning card from his local Co-op on Thursday, June 1.

Mr Bett said he was also looking at using his windfall to go on a trip.

He added: "It will make a huge difference having everything on one level. I will have a conservatory and a garage for storage which means I will have space to take up painting again.

"I used to teach art to children with learning difficulties but I haven't painted for years.

"We've talked about taking a ferry trip to Brussels or France and maybe getting a caravan on the east coast. And of course I'll be looking after my three sisters, too."
