The third umpire is calling no-balls in this match, with a view to doing it for all Test Championship matches.

A gimme from Stuart Broad who, in attempting a yorker, bowls a full toss which Babar Azam drills back past the bowler for four.

Things a little bit flat out there for England, not too much going on for the hosts.

That was a rusty over, a range finder, and there wasn't much turn either.

Dom Bess hasn't bowled in a match since 20 July.

There's a slip and short leg in place for Bess, who didn't bowl a single delivery in that last Test against the Windies.

Too straight and too much bounce as the Pakistan pair take a single each.

So then, Babar Azam comes to England with a strong reputation. He's already starting to show us why he is so highly thought of...

Time for some spin now in the form of Dom Bess...

There is growing talk in the box of end-of-the-world rain arriving at some point this afternoon.

A bit of 'yes' and 'no' as Shan Masood and Babar Azam dilly dally around taking a single. I'm now thinking back to my favourite ever Inzamam-ul-Haq run-outs. There were some right classics.

Another boundary to Pakistan as Masood clips it square. The tourists going along nicely since losing those two quick wickets.

Beautiful from Babar Azam: welcome to the series. Such a classy stroke, and I hope we see lots more of those. That stroke deserved a full-house round of applause.

We once went on a primary school trip to watch Kent play in the County Championship at the St Lawrence Ground. Best school day ever.

The third umpire is calling the no-balls now under new regulations for this series, as Anderson oversteps the mark.

It obviously rattles the England seamer. And to further add to his woes, Babar Azam dispatches him to the point boundary with a scrumptious cut for four.

The Pakistan reserves have just walked around the boundary to the nets. All in line, all wearing identical tracksuits, they looked like they were on a school trip.

Since last summer, Stuart Broad, when bowling round the wicket to the left-hander, has taken 25 wickets at an average of 15.

Broad finds a bit of late shape, there's a noise as it passes Shan Masood and through to Buttler. Replays show it flicked the back leg.

Masood gets a little telling off from the umpire for running down the middle of the wicket as Broad bowls a maiden.

The cameras pan to the Pakistan balcony. They have a real star-studded coaching staff, full of international legends.

Misbah-ul-Haq is the head coach and chief selector, Younis Khan the batting coach, Waqar Younis the bowling coach and Mushtaq Ahmed is imparting his wisdom to the spinners.

The gang is back together.

Slightly ominous signs here for England, as Babar Azam begins to get into full flow.

Well, Andrew, Pakistan are scoring a little bit more freely in these few overs after lunch. Although it's largely down to some wayward bowling from Anderson who again strays down the leg side.

This time it's Babar Azam who flicks it through to the mid-wicket boundary. Easy pickings but well executed.

Andrew Staley: Where are all the complaints from the Pakistan fans about the run-rate? Good Test match cricket in my opinion.

I hear you and am with you on that, Stephan. The BBC live text really is the best place to get things off your chest.

Nicely done by Shan Masood, offered a bit of width by Stuart Broad and the Pakistan opener rocks back and punches through point for a boundary. His best shot of the morning.

While we're on about things being frowned upon or not, I'll get something else off my chest. This job means I spend a lot of time on motorways and therefore stuck in traffic. Is there anything more annoying than motorcyclists weaving in and out of stationary cars? If you're on a motorbike riding between the cars, what lane are you in?

A loosener from James Anderson who bowls full and on the leg side, Babar Azam easily tickling it down to fine leg for four.

A better line from England's all-time leading wicket-taker finds a leading edge off Azam's bat and squirts out to cover for another single.

Anderson ends the over with two dot balls against Shan Masood, a man who (as we've mentioned many times) has struggled against Jimmy.
