England's Harry Brook hit his maiden triple century on the fourth day of the opening Test against Pakistan in Multan on Thursday.

The 25-year-old clubbed a four off spinner Saim Ayub to become the sixth Englishman to score 300 or more in Test cricket, achieving the feat off 310 balls, with 28 fours and three sixes.

England declared their first innings at a mammoth 823-7 before tea for a lead of 267 runs.

Brook notched up a superb 317 and Joe Root hit 262 as both batsmen made their highest test scores on the flat wicket at the Multan Cricket Stadium. (Agencies)
