Euromillions: Adrian and Gillian Bayford win £148m

Adrian Bayford, 41, and his 40-year-old wife Gillian, of Haverhill, won the UK's second biggest ever lottery prize in Friday's lottery draw, Camelot said.

Speaking at a media briefing, Mrs Bayford said she thought her husband was joking when he said they had won.

They have a six-year-old daughter and a son, aged four.

Mr Bayford, who co-owns Suffolk Music Centre in Haverhill, said he convinced his wife that they had both forgotten to buy a ticket when they watched Friday's draw.

He then went and checked the ticket he had bought, with Mrs Bayford describing him as "going a bit pale".

She said: "I checked the numbers on my phone, the TV, the internet - and we just looked at each other and giggled."

Mrs Bayford, a health care assistant at the children's ward at Addenbrooke's Hospital in Cambridge, said they did not sleep that night, BBC News reports.

The couple, who have been married for eight years, spent the night on the internet deciding how to spend the huge jackpot, the result of 14 rollovers.

'Ships in night'

"I find it hard to take in the actual quantity of it," she added.

"We have always worked and saved up for holidays or things that we need.

"We have lived within our means and been comfortable but we have been like ships in the night to earn the income we needed.

"It will be fantastic to spend more time as a family now.

"This money has come at the right time for us and is going to benefit the whole family."

She added: "I'm Scottish, we're known for being tight, I'll still be hitting the sales."

The couple plan to start the search for their dream home, with Mrs Bayford keen to buy the car of her dreams, an Audi Q7.

Her husband said he had always wanted to visit the Canadian Rockies by train, and children want to visit Disney World.

Mrs Bayford, who is originally from Kirkcaldy in Scotland, added: "Children's charities are close to our hearts so we will be exploring how we can use this money to help those charities but it is too soon to say exactly what."

According to The Sunday Times Rich List, they now have a fortune to rival Jamie and Jools Oliver (£150m), Sir Tom Jones (£140m) and Eric Clapton (£130m).

Their win places them 516th in Britain's Rich List.
