Stuart Broad, head band dazzling white in the afternoon sunshine, has the ball in hand to bowl England's second over.

Genuine edge between keeper and first slip. Bairstow didn't move for this, it went to Root's right. I'm not sure whose catch it was.

There is a suggestion it is Bairstow's catch because it wouldn't have carried to Root.

Usman Khawaja swivels on his heels and whips a pull round the corner to notch Australia's first boundary off the fourth ball of the first over.

The penultimate delivery Anderson finds the edge of Khawaja's bat. Neither wicketkeeper Jonny Bairstow, nor Joe Root, at first slip moved as the ball flies through for another boundary.

Was that catchable?

Wallace Poulter: Remember also that Australia have never lost a Test in which Khawaja hit a hundred...

It's outside off stump from James Anderson and hangs in the air allowing Usman Khawaja to dab a single to get off the mark first ball.

Is this more brain-scrambling antics from England?

James Anderson has the 'new' new ball in hand and is at the top of his mark.

Stuart Broad is already muttering about the ball. You haven't actually used it yet, Stuart!

The fourth umpire is running out now - this is absolutely ridiculous!

I can only assume it is not the ball they originally chose and before a ball has been bowled, they're going to change it.

The crowd are rushing back to their seats. They do not want to miss a ball.

The players have emerged from the salubrious Edgbaston dressing rooms and are out on in the middle. David Warner and Usman Khawaja will open for Australia.

England’s Australian bowling coach David Saker has just given each of the England players a pat on the back on the boundary edge. No split loyalties there.

Just attempting to make sense of the afternoon session for a moment.

On the one hand it's a blow to the Australian psyche - in terms of the rest of the series as well as this match - for England's tail end to have wagged.

But on the other, Australia will have seen there's not a great deal in this pitch and might just feel they can pull off this chase.

Going to be a tense evening ahead.

James Lowe: Feels like Australia have had every bit of luck so far. Leach injury, Brooks dismissal, Weather yesterday, missed stumping and drops. Feels like England are due some fortune.

Matt R: For all the talk of bazball, this has in many ways been a fairly classical affair. Either way, a cracking game, well set up.

This is only the fifth time in Test history that 10 players have made it to double figures without a single half-century in the innings.

James Anderson was the last England wicket to fall shortly before the tea interval. Unsurprisingly Pat Cummins was the man to get him - he and Nathan Lyon have shouldered the majority of the burden for the Aussies with the ball.

I was digging through the stats a little earlier. There have only been three successful fourth-innings chases of over 200 runs in Test matches at Edgbaston.

England 378 v India in 2022.

South Africa 281 v England in 2008.

England 208 v New Zealand in 1999.

Australia did, of course, famously fall three runs short of chasing 282 on this ground in the 2005 Ashes.

Thanks, Tom. Phew, take a breath.

Another thoroughly absorbing session of Ashes Test cricket.

Well, that was fun.

Time for me to take a break but here to guide you through what promises to be another exciting final session is Timothy Abraham.

The Burnley Lara strikes again.

You feel England have left some runs out there, but had you offered them 280 at the start of the day they would have taken it.
