A couple aged 68 and 73 who won $4.8 million in Saturday's Lotto said they would stay in their house and will leave their lifestyle unchanged despite their newfound wealth.

The "noveau riche" pensioners identified as John David, 68 and his wife Pat, 73, of Portsmouth, Hants have insisted on driving their old car, a Vauxhall Astra.

According to the Sun, "We might be millionaires but we still want to do what we did before," John said.

"If I was younger I would consider going out and spending money on posh cars and things, but not at my age.

"As long as my car gets me from A to B, it's all I need. We want a normal life in a normal home with our family and friends."

But they are giving themselves some luxury. The couple is scheduled to visit Singapore on a holiday where John served as a medic during his stint in the Royal Navy.

They said they plan to give some of the cash to charities and provide for their two daughters, five grandchildren and five great grandchildren.
