Some of you getting in touch about how Root's dismissal could have swung things firmly in Pakistan's favour. Time will tell, but if you missed that wicket here's another chance to catch up.

Bit of a languid spell developing. Yasir has an even-split in the field. Meanwhile, Mohammad Amir took a short break from proceedings and is now ready to come back on. Wonder if he has to fervently signal the umpire to be let back on, like they do in the footy? Or is it just a quick and polite change between overs?

Bairstow has been in tremendous form, but the last couple of innings he's come out and played like a man on 150 not out.

Two slips for Rahat, as the wind looks to be picking up. Bairstow strokes one through mid-off and a diving Misbah on the circle prevents the four.

Skipper has been all over this game and he also has time to give Rahat a quick word of advice in between deliveries.

The cupcakes were nice. But the real question is should I finish the last one or leave it for one of my colleagues?

Bairstow is trying something from every ball - he just needs to get himself in.

Yasir loves to have a quick lick of his fingers during that short run-up. He must be licking his lips as Bairstow leans forward and misses one that is close to the stumps. Yasir's sweat bands are still pristine white, must be said.

Speaking of licking lips, somebody has just left a tray of cakes next to me.

Six-packs are overrated.

That went low to and to his right. Not much of a shot from Bairstow. It bounced just in front of Younus.

Rahat sees a half-chance in his first over after the interval. A thick edge off Bairstow doesn't quite carry to slip. The Yorkshiremen then has a problem with the sight screen before Yasir's next over.

"They called me maaaaad". No really, someone did call me mad earlier when I said my lunch was soup and coffee. Alright then, I'll have a bit of wine and cheese then shall I? Well, maybe later.

"You get the felling that England are going to have these periods this summer, when they lose wickets in clusters. When this Pakistan attack are hot, they're hot."

Pakistan much chirpier understandably. More encouragement in urdu going around the players - "same way, same way" from the wicketkeeper to Yasir, who starts with a maiden.

My favourite form of 'encouragement' of all time, has got to be the stare down any bowler gets from Mahendra Singh Dhoni when something goes wrong. Even through his awesome shades, you can feel yourself being pierced.

Pakistan's players are back out for the final session. Although Misbah holds them back just inside the boundary rope for a team-talk. Plenty of intent faces, clapping, and then they disperse. 

Alastair Cook and Jonny Bairstow follow the visitors out. Yasir Shah will have the ball.

Pakistan have not had it all their way, of course. They have dropped Alastair Cook twice, and both off Amir's bowling. The second of those you can watch here. Slightly painful viewing also if you're wicketkeeper Sarfraz Ahmed.

If James Vince's lbw decision was marginal, then it was the opposite for Gary Ballance, making his return to Test cricket. You can watch it again below.

Full scorecard

England's afternoon was going along nicely when they advanced to 118-1, with Alastair Cook and Joe Root looking in total control.

However, Root misjudged a sweep shot and a top edge flew into the air to precipitate a collapse.

James Vince, despite a couple of sweetly-struck boundaries, and Gary Ballace were then struck in front by leg-spinner Yasir Shah.

It could have been even better for Pakistan, who have dropped Alastair Cook twice off Mohammad Amir's bowling.

England's young batsmen aren't putting much in their credit account when you think that they will soon be heading to Bangladesh and India but they are getting out to leg-spin at Lord's when there's only a little turn.

I was thinking earlier about how England's batting has mirrored Pakistan's first innings. And I'll tell you what, Pakistan were 134-4 before Asad Shafiq and Misbah began their superb partnership. Could be an omen, with Bairstow at the crease, who can probably give Misbah a run for his money on the beard category.

More drinks on show (what is it about this five bottles in a row? Something I've missed), as they toast England crossing the 150 mark. And that's also Tea!
