England leg spinner Rehan Ahmed has become the youngest man to take five wickets in an innings on Test debut, putting his team on course for a comfortable victory in the third and final Test against Pakistan in Karachi.
With two days of play remaining, England need 55 runs to win the Test and become the first Test team to complete a 3-0 whitewash in Pakistan, having won the first two Tests in Rawalpindi and Multan.
