Pakistan have a last-minute huddle before making their way out to the middle, followed by Dom Bess, on 40, and Dawid Malan on 27.
By the looks of things, Shadab Khan will start the post-tea proceedings.
Cheers, Jack. There's 32 overs left in the day and theoretically we can go through to 19:30.
Buckle up. It's going to be a long one.
Right, with tea nearing an end, that's me off. I'll hand you over to Amy Lofthouse to take you through the final session. Cheers.
Not that it's all been Bess.
After a slow start, Dawid Malan has played some cracking shots too, their partnership now worth 61...

Dominic Booth: Has a nightwatchman ever watched two nights with the same innings?
Despite losing his skipper, Bess has continued to look assured, belying his supposed role of nightwatchman and looking a talented batsman...

England have brought better concentration this week. All the batsmen have got in. Dom Bess is a revelation. He looks so controlled. He's got a really good cricket game and plays it with a lot of maturity.
So after the first session of day two was wiped out by rain, play finally got under way at 14:45 BST.
Joe Root and Dom Bess made steady progress until the England captain nicked Mohammad Amir behind to fall for 45...

England are in a mighty fine position. The chalk and cheese expression comes to mind, with the performance at Lord's, and then this.
Lead by 25
Scratch that, the very next ball is short and Malan pulls it down and away to deep mid-wicket for a single.
Faheem goes short to Bess, who gets up on his toes and fends it down.
Final ball of the session and Bess plays an authoritative forward defence.
Excellent stuff from the 'nightwatchman' - he gets through to tea on 40 not out, with Malan unbeaten on 27. England are 199-3, leading by 25.

Dom Bess, the veteran, is now coming down to have a word with his partner.

Ooft. Dawid Malan tries to pull a short ball but misses and it deflects off the side of his helmet and away to gully. Probably best to shelve that shot before the interval.

Pakistan are just getting a little something going here. They're building a few dots. England have got to hang in and get to tea.

That's turned a long, long way. It went from outside off to well outside leg.
Bess 40, Malan 26
Hello! Shadab Khan gets one to spit out of a foothole and spin sharply from off stump to past Dawid Malan's back.
Encouraging signs for the spinners later in this Test?
Bess and Malan add a single apiece to the total.
Image source, AFPDawid Malan continues to bat well out of his crease to the medium-fast bowlers, having struggled against seam bowling in Tests at home when he gets caught playing tentatively on the crease.
He's looking much more purposeful today, not least in this wonderful straight drive.
For now, he's happy to defend, playing out a maiden over from Faheem Ashraf.

I'm on the Western Terrace, sitting next to some monks. The smell of ale is in the air and one chap has just slipped on the stairs. He dropped his cap, but saved his pint. The chap behind me says: "After another couple of beers, this place is going to erupt."

It's starting to get a bit rowdy on the Western Terrace. They've had a long day.

Malan clips another through mid-wicket for one.
