This British couple not only blew their multimillion-pound lottery win but also saw their marriage collapse as a result. Lara and Roger Griffiths fully embraced the luxury lifestyle after their £1.8 million ($2.3m) windfall in 2005, but raucous spending and bad investments quickly caused disharmony between the pair.

The Griffiths’ 14-year marriage came to an end when Roger moved out, and a week later he revealed that their fortune was all but gone. In 2013 he told The Sun newspaper he had just £7 ($9) to his name, while Lara was surviving on financial support from her mother.
