Spinner Abdur Rehman took six wickets as Pakistan beat England by 72 runs in the second Test on Saturday to clinch the three-match series, bowling out the tourists for 72 in their second innings after another abject batting display.
England, the number one test side in the world, had earlier dismissed Pakistan for 214 to give themselves a target of 145 to win in Abu Dhabi.
But Andrew Strauss's men again failed to deal with the host's triple spin threat of Rehman, Saeed Ajmal and Mohammad Hafeez.
Rehman ended on 6-25, while Ajmal's figures were 3-22.
Only Strauss (32) and Matt Prior (18) managed double figures, the tourists losing all 10 wickets in the space of 22 overs.
Alastair Cook (7) was the first to go, caught and bowled by Hafeez, who stooped to get his fingers to the ball inches from the turf. Ian Bell (3) came in at number three in place of Jonathan Trott who had been off the field with a stomach complaint and the Warwickshire batsman lasted just three balls before deflecting an Ajmal delivery on to his stumps with an inside edge.
Kevin Pietersen (1) and Eoin Morgan (0) then continued their miserable form, falling to Rehman in the space of three balls. Pietersen was trapped lbw after lunging forward to defend, while Morgan saw his leg stump felled. Strauss had earlier escaped, deflecting a Rehman delivery off his bat and pad to Azhar Ali at short leg but finally went lbw to him, as did the returning Trott (1), while the slow left-armer clean bowled Broad through the gate as England offered little resistance..
Brief scores: Pak & 214 (Ali 68; Panesar 6-62) v Eng 327 & 72 (Rehman 6-25)
