That's it from us after a frankly bonkers day in Multan.

Records galore for England with the bat, led by a sparkling triple century from Harry Brook, before the bowlers got stuck into Pakistan late in the day.

All of which has put Ollie Pope's side on the brink of a famous win - you can read Stephan Shemilt's report from Multan here.

We'll be back bright and early tomorrow as England try to wrap things up.

It could happen quickly and play starts at 06:00 BST so join us then if you don't want to risk missing all the fun!

England batter Joe Root, speaking to BBC Test Match Special, on breaking records: "They are pretty cool things. It would mean a lot more if we can win this Test match. You look at the situation where they had 556 on the scoreboard and to be this ahead in the game is the best thing.

"So many good things have come from it and I am very pleased for [Harry] Brook. I've never seen an England batter get a 300 and that was nice to watch."

On becoming the all-time runscorer for England: "It doesn't mean a lot at the moment. I feel like I am going to play a lot more cricket for England.

"It's obviously nice and I am sure when I finish my career, I will look back and feel good about it. It will be a nice thing to look back on at the right time. I want to contribute for a long while and make big scores like this one and hopefully win more Test matches for England."

On muted celebrations: "There was a lack of emotions, partly down to the heat. Just the amount of energy that is taken out of you playing in these conditions is huge. It's been quite pleasing to acclimatise and just drawing that mental resilience.

"I make sure I do the work and put myself in some really tough situations in training so that I am really ready for these conditions. I know I can bat for long periods of time and when it gets tough, I can get through it."

England batter Joe Root, speaking to BBC Test Match Special: "It's been a phenomenal couple of days from the team. That last session was a huge feat.

"To take 10 wickets on a pitch like that and then put ourselves in a position where we have a real chance to win the game tomorrow now is a testament to the work ethic of the group and our ability to exploit the conditions."

On Harry Brook's innings: "It was a brilliant day. [Harry] Brook was outstanding.

"Everyone who spend time on the wicket has looked good and made the most of a good batting wicket. It was nice for us to get together and keep the partnership going.

"I think we keep each other going. We have a good laugh out there in the middle. We have played a lot of cricket together whether it be for Yorkshire or for England. He's fun to play with."

What a treat it has been to watch these two bat over the past couple of days.

We're hoping to hear from them both shortly after their magnificent 454-run partnership...

Joe Root ran so much today. He did the really difficult job building those partnerships with Zak Crawley and Ben Duckett, promoted up to number three where he doesn't ideally like batting.

He had to do a lot of work in the early parts to negate Pakistan.

Whenever Pakistan's energy went up, Root sucked the energy out of them and he earned the right to score those runs and laid the way for Harry Brook to go on and play that innings.

It was a wonderful lesson in subcontinental technique, concentration and skill. It's befitting he went past Sir Alastair Cook in that innings as well.

As soon as Pakistan lost their first wicket, it seemed inevitable that it was going to continue to happen.

When you lose a wicket in the first ball, everyone's scrambling around in the dressing room. They are chaotic places when that happens.

I think Ollie Pope has had a good first innings as a captain though they conceded 556. They could've waited until tea to make that declaration.

When he decided to do it 25 minutes before tea, it gave Pakistan no chance to mentally prepare for the bat. You've got to give him credit for that.

The good folks at CricViz also provided us all the key statistics from England's somewhat ludicrous first-innings 823-7 declared...

• The 454-run partnership between Joe Root & Harry Brook was the highest partnership for England and the fourth-highest overall in the history of Test cricket
• This was only the third instance of two batters scoring 250-plus runs in the same innings and the first time for England
• Both Joe Root and Harry Brook registered their highest individual Test scores scoring 262 & 317 respectively
• Joe Root went past Alastair Cook’s tally of 12,472 runs to become the leading run-scorer for England in Tests
• Harry Brook became the sixth English batter to score a triple century and was the second-quickest batter to that landmark in the history of Test cricket having reached there in 310 balls
• England’s 823-7 declared was the fourth-highest score in the history of Test cricket and the highest against Pakistan by any nation. Their lead of 267 runs is also the most for any team after having conceded 550+ runs in the first innings

At the end of day four this pitch has a PitchViz rating of 2.9 which makes it the eighth-flattest pitch for the first four days of a Test in the ball-tracking era.

There has been average swing of 0.63 degrees - that is the lowest in any Test in Pakistan since the start of 2022.

There is average turn is 2.86 degrees. That is the third-lowest in the same time period.

What a day.

England posted 823-7 declared in their first innings, Joe Root scored a career-best 262 but then watched Harry Brook go past him to become just the sixth England player to score a Test triple hundred.

A flat, flat pitch then? Well, yes, but Pakistan then managed to collapse to 82-6 before a battling seventh-wicket stand spared them an embarrassing four-day defeat.

England have had an outstanding day and Pakistan have had a terrible day. There's been some really, really soft dismissals. And you have to question why?

Is it because of their fitness? Is it their concentration? What has made Pakistan very different from their first innings?

Salman Ali Agha pinches a single to point from the last ball of Shoaib Bashir's over - and that is stumps.

A useful partnership of 70 between Salman and Aamer Jamal has held up England's push for victory.

But, after an extraordinary and record-breaking fourth day, the tourists will be confident of wrapping it up on day five.

Jack Leach is on the money to Aamer Jamal, who is eventually able to work a single from the fifth ball.

Salman Ali Agha then delays before the last ball but not for long enough.

England race round to squeeze in one more over before stumps.

Such an ugly shot and one that is not really needed from Salman Ali Agha. It got him four but it could have gotten him out as well.

Jack Leach comes on to bowl what may well be the last over of the day.

It's been a bit of a struggle for Shoaib Bashir in this match.

The consistency just hasn't been there so he's been unable to really build any pressure.

An expensive over ends with Salman Ali Agha skipping down and hacking the ball leg side for four.

The time is ticking towards half past five here, but if another wicket was to fall, there is the possibility of claiming some extra time. England might get another couple of overs with the light fading.
