A one-off National Lottery draw will create 100 millionaires as a "thank you" to players for helping fund the London 2012 Olympic and Paralympic Games.
The EuroMillions Millionaire Raffle draw will take place on the night of the opening ceremony of the Olympic Games on July 27, a National Lottery spokesman said.
The event guarantees a million-pound cheque for 100 UK players, breaking the world record for the most millionaires created in a single draw.
National Lottery players are contributing £2.2 billion towards the staging of the London 2012 Games, including venues and infrastructure.
The spokesman said: "The opening ceremony will be a huge night for Britain and this amazing draw is set to add to that excitement, making it truly a night to remember.
"We will see 100 UK players become millionaires as the torch is lit above London, smashing the world record for the most millionaires created in one night.
"National Lottery players are playing a key role in the London 2012 Games, helping fund both the infrastructure and venues, and provide life-changing support to athletes. This special one-off draw celebrates their role in helping bring the Games to London."
The previous record for million-pound winners in a single draw was set after 25 players won in the EuroMillions Millionaire Raffle draw on Christmas Eve in 2010.
The map was commissioned to mark Tuesday night's EuroMillions roll-over which is now a staggering £138 million - the fifth biggest jackpot ever offered in the UK.</p>
Should anyone scoop the jackpot, their wealth will be slightly less than Europe's biggest Lottery winners Colin and Chris Weir, from Largs in Ayrshire. The husband and wife made the headlines in July when they won £161,653,000, thanks to several rollovers.</p>
Boasting 164 National Lottery millionaires, one in 14,211 North East residents has now banked a seven-figure jackpot prize. Winners Paul and Christine Goldie from Washington, near Sunderland, pocketed £3,581,481 after their numbers came up on Christmas Day last year.</p>
The Millionaire Map, which includes both publicity and non-publicity winners, is based on the number of millionaires created per adult population. One man who did go public with his winnings was Wayne Hughes from Holyhead on Anglesey, north Wales. The shop worker scooped £1,117,779 last August and even had the winning numbers tattooed on his arm.</p>
The region with the fewest millionaire jackpot winners was Northern Ireland, where only 53 seven-figure or more winners were created.</p>
Wales has seen 179 millionaires - one person in 14,502 - created over the last 16 years. Rugby fans Terry Roberts, Mike Williams, Lance Gifford and Gerwyn Jones, from the Rhondda Valley in south Wales, split £4,091,609 in April this year.</p>
