Defeat at Lord's is not something Australia are accustomed to. The last time it happened was 1934, but unless Ricky Ponting's side can produce heroics in the last two days of the Second Test, that will be their fate.
Escape to victory would almost certainly involve batting for most of that time, and they would have to eclipse the world record total for a final innings to win a Test – the 418 for seven recorded by West Indies against them in Antigua in 2002-03.
Matthew Prior led England's ruthless drive towards a match-winning lead. The wicketkeeper-batsman hit a superb 61 off only 42 balls and typified the desire to capitalise on their dominance, something the Australians failed to do in Cardiff last week.
Prior's brilliant innings, which included nine boundaries, helped England progress into a daunting 521-run lead at the end of the third day after England reached a commanding 311 for six.
