London: England crushed Australia by 347 runs at Lord's to take a 2-0 lead in the series and tighten their grip on the Ashes urn.
The hosts bowled Australia out for 235 late on the fourth day, having set them a notional 583 to win after declaring on 349-7 when Joe Root was dismissed for 180.
The tourists' last-wicket pair frustrated England for an hour and threatened to take the match into a final day.
But with just four balls remaining before a delayed close, Graeme Swann trapped James Pattinson lbw for 35 to send England's players into delighted celebrations.
The off-spinner finished with 4-78, and nine wickets in the match, while Tim Bresnan, James Anderson and Root took two wickets apiece.
Once again, the day featured controversies over the decision review system - Steve Smith and Ashton Agar fell to marginal calls - but there was no masking the gulf in quality between the sport's two oldest rivals.
The resounding victory, England's third biggest in terms of runs, puts Alastair Cook's team in a commanding position from which to win their third Ashes series in a row.
Don Bradman's 1936-37 Australians are the only team in the 136-year history of Test cricket to have come back from 2-0 down to win a series.
Australia, set a mammoth 583 for an improbable victory, were dismissed for 235 on the fourth day.
The tourists' last-wicket pair of James Pattinson and Ryan Harris held firm for more than an hour, with England claiming the extra half hour.
But with just three balls left in the day's play, off-spinner Graeme Swann had Pattinson, who had frustrated England with the bat in their 14-run first Test win at Trent Bridge, lbw for 35 to the acclaim of a capacity and sun-drenched crowd.
Swann finished with innings figures of four wickets for 78 runs for a match haul of nine for 122.
The scale of Australia's task was clear from the fact that no side have made more to win in the fourth innings of a Test than the West Indies' 418 for seven against Australia at St John's in 2002/03.
Man-of-the-match Joe Root starred with both bat and ball, making 180 in England's second innings 347 for nine declared before the occasional off-spinner took two wickets shortly before tea to spark an Australia middle-order collapse.
