England edged ahead at the end of the first day of the third Test against Pakistan after 16 wickets fell in a tumultuous opening to the dead rubber contest.
Stuart Broad and James Anderson were the pick of England's bowlers as Pakistan were bowled out for 99 after choosing to bat first. Yet England could only take a minor advantage into the second day after they finished on 104-6 at the close, a lead of only five runs.
At 2-0 down, England are anxious to avoid a series whitewash that could, with South Africa close behind, derail them as the world's No.1 ranked Test side.
The tourists got off to an auspicious start, with Anderson (3-35) and Broad (4-36) claiming five wickets between them in the first hour. Only Asad Shafiq, batting at No.6, provided any sustained resistance. But when he was trapped lbw by Panesar on 45, Pakistan were already eight down and facing the prospect of a huge first-innings deficit.
However, England's brittle batting line-up succumbed yet again to the vagaries of Pakistan spin as they stumbled through to tea at 7-2.
Alastair Cook, typically a stoic leaver of the ball outside off, chased after a wide ball from Umar Gul and was caught spectacularly by a diving Adnan Akmal. England lost their only other consistent batsman soon after when Jonathan Trott fell lbw to the same bowler.
Strauss and Pietersen briefly offered England some respite with a third-wicket stand of 57 before the latter became the eight lbw victim of the day - falling, once again, to a slow left-arm spinner. Ian Bell and Eoin Morgan fell soon after, before Matt Prior rounded off a miserable England batting display when he was bowled by Abdur Rehman's orthodox spin.
