The holder of a EuroMillions lottery ticket worth £35.4m is to be unveiled at a Scottish hotel later.
A Royal Mail worker has described herself as "flabbergasted" after landing the UK's biggest lottery prize.
Newspapers have reported that she is 40-year-old postal worker Angie Cunningham from East Kilbride.
Angela Kelly, 40, from East Kilbride, South Lanarkshire, scooped £35.4m in Friday's EuroMillions draw, but was not aware of her win until Monday.
The prize is the biggest single payout in the UK's Lottery history, according to Camelot, which operates the British arm of the European draw.
The lucky dip ticket was in her handbag and she only checked it when she realised the cash had gone unclaimed.
The winner waited until Tuesday to claim the record jackpot, after matching the numbers in Friday's draw.
Ms Kelly, who lives with her 14-year-old son, said she would quit her job at a Glasgow sorting office.
In her handbag
The transport manager, who earns £21,000 annually, would have taken about 1,500 years to earn the amount of her win.
The numbers drawn on Friday 10 August were: 23, 40, 42, 43, 49. The lucky star numbers were two and six.
'In limbo'
It was reported that Ms Cunningham lives with her 14-year-old son in a two-bedroom flat.
Ms Kelly, who has been separated from husband Gerry for eight years, uses her maiden name Cunningham at the Springburn depot, where she has worked for 24 years.
She paid £1.50 for a lucky dip ticket for Friday's draw but did not know she had scooped the jackpot until Monday.
She said she was still deciding how to spend her winnings.
The ticket was in her handbag and she only checked it when she realised the cash had gone unclaimed.
"I feel totally in limbo. I just need to sit down to get my thoughts together," Ms Kelly said.
Ms Cunningham has reportedly told colleagues at Glasgow's Springburn sorting office she will not be coming back to work as a transport manager.
"My son does not want to move out of the flat and I don't want to move too far away because he is going into fourth year at school."

I couldn't even say anything, I just pushed my chair back and put my head between my knees Angela Kelly
According to reports, Ms Cunningham is separated from husband Gerry, who worked with her at the Glasgow postal depot.
During a media conference at Airth Castle near Falkirk, Ms Kelly described how she had bought the ticket in Sainsbury's on Thursday but forgot to check the numbers the following day.
In July 2005, mother-of-six Dolores McNamara, of Limerick, Ireland, won £77m, and in February 2006 three ticket holders won a share of £126m.
She said she was out with girlfriends on Saturday and spent Sunday sitting in front of the TV.
It was only on a break from work on Monday that she remembered to check her ticket.
She asked five colleagues to check that she had won because she could not believe it.
"I couldn't even say anything, I just pushed my chair back and put my head between my knees, I was so flabbergasted," Ms Kelly said.

I think it's fantastic that a normal, hardworking down to earth person has won! I'm so pleased for her and I hope she has a wonderful time spending her winnings! PS I bet her hubby is gutted!Lisa, Essex
I pray that she and her son remain level-headed, that they stay in their flat to look after his education that they keep to the values of hard work and happiness. How would I spend it? I couldn't! A lot of small charities would benefit if I won that kind of money.Paul, Leeds
Why in the world would anyone go public over that kind of win? Bruce Swift, Leamington Spa, England
As a newly wed. I would buy a nice home with my husband, have lots of children and we both could retire early.Tracy, UK
I would go on a long holiday first to make a list of people I want to give a lump sum to, family would be well looked after. Then I would definitely donate some to my favourite charities, and buy a lovely big house and employ a full time house keeper. But I don't think I would be any happier than I am today. Money DOES NOT buy happiness.Lynda Barnett, Isle of Man
I would invest the money into a small business or even start property developingMichelle, Cardiff, South Wales
I would give mojority to the poor and needy, and not remain selfish like some.Nadeem Sharif, Sheffield
