Rehan Ahmed drags one down and Nauman Ali confidently pulls away for four.

Three balls later it is the same delivery with the same result. It worked to get Babar, but Nauman wasn't falling into that trap this time.

Rehan slaps his hands in frustration as he looks at a replay of the shot on the big screen.

Valuable runs for Pakistan though.

I am surprised they took off Root. He bowled a lovely over before he got the wicket. You thought he might find the outside edge again but Stokes knows better.

A huge appeal from Jack Leach. He thinks Salman Agha has feathered an under-edge behind to Ben Foakes, but the umpire says no.

Ben Stokes runs in for a quick chat but declines the review, with the replay showing that was the correct call.

Despite taking a wicket in his first over after tea Joe Root is out of the attack - Jack Leach is back.

Ruthless from the skipper.

Rehan Ahmed bowls around the wicket to and completely outfoxes Nauman Ali with a googly that spins away from the new Pakistan batter and flashes past his outside edge.

Nauman and Salman Agha share a couple of unconvincing singles.

It feels like another wicket could fall at any moment.

Another left hander, Nauman Ali, is the new batter.

He too is tempted into a wafty cut outside his off stump and very nearly edges through to Foakes.

Nauman gets off the mark with a push to gully for a single to keep the strike next over.

Pakistan in a bit of a hole now.

He didn't wait for the reviewing. The situation for Pakistan has reached critical.

Rehan Ahmed lands one on that teasing length, getting some grip and turn before beating the outside edge of Salman Agha's bat.

It will be twin spin to start the session with Joe Root bowling at the other end.

Rehan Ahmed will bowl the first over after tea. It should be a slightly longer session given we should have enough light to get the required overs in.

Thanks, Matthew.

Three quick wickets in the morning, three quick wickets in the afternoon. Three more quick wickets here and England could be on the brink.

The pressure will be on Salman Agha to guide the tail and try and get Pakistan up to a defendable total.

How many more could Rehan Ahmed get in this session?

England could go a long way to sealing victory - and a historic clean sweep in Pakistan, remember - in the next couple of hours.

Rehan Ahmed is younger than Strictly, Facebook and professional T20 cricket.

Now he's getting England fans excited.

By playing in this Test he became England's youngest men's Test cricketer, doing so despite having just three first-class matches to his name.

He impressed in the Under-19 World Cup earlier this year and on the back of that was signed for £60,000 by Southern Brave in this year's Hundred.

He grew up playing cricket with his two brothers in the garden. Aged 11 was invited to bowl at England's batters in the nets at Lord's.

Now he's making his mark on the biggest stage.

It felt like this game could go five days. England have opened that door with Rehan's quick wickets and they are back in the game.

Pakistan lost 3-13 there - all three of the wickets to Rehan Ahmed.

They lost 3-1 - all to Jack Leach - in the morning session.

All the wickets have been taken by spinners today.

A maiden for Leach ends the session.

Pakistan were three down, leading by 114 at one stage with Saud Shakeel and Babar Azam at the crease.

Then Rehan Ahmed arrived.
