England extended their overall lead over Australia to 267 with all second-innings wickets intact after declining to enforce the follow-on on the third morning of the second Ashes Test at Lord's on Saturday.
At lunch, England were 57 for no wicket in their second innings with captain Andrew Strauss (24 not out) and Alastair Cook (32 not out) taking full toll of some short-pitched bowling from the Australian pace attack.
Australia, 156 for eight overnight in reply to England's 425, were bowled out for 215.
The visitors batted brightly on a sunlit morning with Peter Siddle reaching his highest Test score of 35.
Neither Siddle nor his partner Nathan Hauritz looked unduly troubled by the England pace attack with Stuart Broad bowling a stream of ill-directed bouncers from the Pavilion end.
James Anderson, who started the day with figures of four for 36, was more accurate but was not able to get the late swing which troubled the Australian batsmen on Friday.
Graham Onions took over at the Nursery end and made the breakthrough with his third ball which Hauritz (24) steered to Paul Collingwood at third slip.
Siddle continued to prosper at Broad's expense, guiding one delivery to the third man boundary and hooking another to fine-leg.
He was finally out after batting for more than an hour with five fours when he edged Onions to Strauss at first slip.
England began positively in their second innings as they sought to get a substantial lead while giving themselves plenty of time to bowl out Australia and win their first Ashes Test at Lord's since 1934.
Strauss thumped a four to the mid-wicket boundary in Ben Hilfenhaus's first over and Mitchell Johnson was again disappointing, conceding 17 runs from his opening three overs.
