England have retained the Ashes for the first time in 24 years - and with a match to spare - after easing to a comprehensive win in the fourth Test played at Melbourne Cricket Ground (MCG). Australia, resuming 246 runs behind on 169-6 and with Ryan Harris unable to bat, were eventually dismissed for 258 before lunch on day four. Chris Tremlett, Graeme Swann and Tim Bresnan each took a wicket as England won by an innings and 157 runs. The tourists are now 2-1 up with only the Sydney Test remaining. If they avoid defeat there, England will win their first series down under since 1986/87.
