Stokes scored a test record for a number six batsman and starred in a record sixth wicket partnership of 399 runs with Jonny Bairstow, who was 150 not out when England declared.

“It hasn’t really sunk in yet, and quite a lot of adrenalin is running through me, but at this moment in time, I don’t know, I’m pretty tired."
