England became the first test team to complete a 3-0 whitewash in Pakistan after they won the third and final match by eight wickets in Karachi on Tuesday.
Having restricted Pakistan to 216 in the second innings England comfortably chased a target of 167 to add to their victories in Rawalpindi and Multan.
Zak Crawley (41) and Ben Duckett (82 not out) made an 87-run opening partnership to give England a flying start before Abrar Ahmed trapped Crawley lbw.
England all-rounder Rehan Ahmed, promoted to number three, made 10 runs before the leg spinner lost his off-stump, but a 73-run partnership between captain Ben Stokes and Duckett sealed the win during the morning session of day four.
