Pak stumble, England tumble
Hosts hit back strongly after getting bowled out for 99 on opening day
Sixteen wickets tumbled on the opening day of the third third and final Test as England limped to 104 for six after skittling hosts Pakistan for 99. 
After slumping to 44 for seven at one stage, Pakistan closed the day reasonably happy after their spinners again gave England's batsmen a torrid time.
Slow left-arm spinner Abdur Rehman removed Kevin Pietersen, Eoin Morgan and Matt Prior while Saeed Ajmal accounted for Ian Bell for the fourth time in five innings in the series.
Pietersen's dismissal set a record for the most leg before wicket dismissals in a three-match series -- surpassing the 33 in the 1993 contest between the West Indies and Pakistan.
Captain Andrew Strauss held firm on 41 at the close, to give England some hope of cashing in on a superb performance by the their pace attack in which Stuart Broad and James Anderson sparkled.
Broad was in scintillating form, ripping through Pakistan's top order as the hosts collapsed to 53 for seven at lunch after winning the toss and electing to bat.
He took four for 21 in a devastating spell as England looked to restore some pride after heavy defeats in the opening two matches. New ball partner Anderson got England off to a perfect start when he struck with the last ball of the first over, removing Taufeeq Umar with a regulation leg before decision.
Broad was soon among the wickets when he trapped Azhar Ali in his third over, the batsman sent back to the pavilion when a TV review showed he had feathered a catch through to wicketkeeper Matt Prior.
It was also a poor morning for umpire Simon Taufel, who had a second not out decision overturned by an England review when Mohammad Hafeez was given out lbw to a Broad delivery that was clipping leg stump to leave Pakistan four down.
His counterpart Steve Davis was having a better time of it and was vindicated after two Pakistan reviews -- the first ordered by captain Misbah-ul-Haq and the second by Adnan Akmal -- both backed up his decision to give them out lbw.
In between the two Taufel reviews, Younis Khan played a loose shot outside off stump to a Broad lifter and when Abdul Rehman gifted spinner Graeme Swann his wicket 20 minutes before lunch, Pakistan were reeling on 44-7 and in danger of not reaching their lowest test total of 53, scored against Australia at Sharjah in 2002.
Asad Shafiq, in tandem with Saeed Ajmal, provided the only real resistance with a fluid innings of 45 which ended shortly after the afternoon drinks break when he attempted to cut a straight one from Monty Panesar which hit him on the back pad.
After Shafiq's exit, Umar Gul entertained the small contingent of Pakistan fans with a brief cameo -- including one huge six off Panesar -- before Anderson rearranged his stumps to bring the innings to a close with his third wicket.
