England [ Images ] declined to enforce the follow-on after dismissing Australia [ Images ] for 215 on the third morning of the second Ashes Test at Lord's in London [ Images ] on Saturday.

Australia, 156 for eight overnight in reply to England's first innings 425, batted brightly with Peter Siddle [ Images ] reaching his highest Test score of 35.

Neither Siddle nor his partner Nathan Hauritz [ Images ] looked unduly troubled by the England pace attack with Stuart Broad [ Images ] bowling a stream of ill-directed bouncers from the Pavilion end.

James Anderson [ Images ], who started the day with figures of four for 36, was more accurate but was not able to get the late out-swing which troubled all the Australian batsmen on Friday.

Graham Onions [ Images ] took over at the Nursery end and made the breakthrough with his third ball which Hauritz (24) steered to Paul Collingwood [ Images ] 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 England captain Andrew Strauss [ Images ] at first slip.
