England won the third and final match by eight wickets on Tuesday in Karachi, becoming the first test team to win all three games in Pakistan.
With ease, England successfully chased down a score of 167 to add to their victories in Rawalpindi and Multan after restricting Pakistan to 216 in the second innings.
England got off to a fast start thanks to an 87-run opening partnership between Zak Crawley (41) and Ben Duckett (82 not out), but Crawley was eventually bowled by Abrar Ahmed.
However, a 73-run partnership between skipper Ben Stokes and Duckett during the morning session of day four secured the victory. England all-rounder Rehan Ahmed, who was moved up to number three, made 10 runs before the leg spinner lost his off-stump.
