Federer surrenders two-set lead to crash out of Wimbledon

Roger Federer let a two-set lead slip away as he was sent careering out of Wimbledon by inspired Frenchman Jo-Wilfried Tsonga.

A quarter-final match which became a sensational Centre Court contest did not begin that way, with Federer easing through the first set and then taking a one-sided tie-break in the second.
