Buttongate 

Jenson Button's contract saga in 2004/2005. Button signed a contract to drive for Williams in 2005, despite having a contract with BAR for 2005. A giant legal battle followed, to determine who Button would drive for in 2005. This became known as Buttongate I.

Button wanted to remain with BAR for 2006. However, in the summer of 2004, Button signed a contract with Williams to drive from 2006 onwards. Another legal battle began. This became known as Buttongate II.

"Avoiding another potential Buttongate, Williams signed GP2 superstar Nico Rosberg.
