England were rampant, Pakistan feeble. The hosts disintegrated after tea, spiralling towards a humiliating defeat on 152-6, still 115 short of making England bat again.
Never before has a team posted so many runs in the first innings of a Test, then gone on to lose by an innings.
Multan madness - the records that fell
Brook became the sixth English batter to score a triple century and first since 1990. It was the second-fastest 300 of all time, reached in 310 deliveries.
The 454 that Root and Brook added for the fourth-wicket is England’s highest partnership for any wicket, the fourth-highest in all Test cricket and best for the fourth-wicket.
Root’s double century was his sixth in Test cricket, only Wally Hammond, on seven, has more for England.
This was only the third instance in Test history that two batters passed 250 in the same innings and the first occasion for England.
England’s 823-7 declared is the fourth-highest team total in Test cricket and England’s highest since 903-7 declared against Australia at The Oval in 1938.
England’s lead of 267 runs is the most for any team in Test history after conceding a total in excess of 550 in the first innings of a match.
