pounds 85m top prize in new draw.
Camelot said that a single UK winner would rival the bank balance of pop star Robbie Williams, who was valued at pounds 90 million in The Sunday Times Rich List 2010.
The lucky winner would take second place on The National Lottery Rich List behind last year's EuroMillions winners who banked pounds 113 million in October.
The introduction of the Tuesday draw is one of several changes to EuroMillions, including a new prize tier of around pounds 2.70 for matching two main numbers. There is also a choice of 11 Lucky Stars instead of nine.
