So the West Midlands bragging rights belong to Birmingham City tonight.

West Brom will go home feeling mightily aggrieved and with plenty of time to lick their wounds, with a fortnight to wait until they are next in action.

There are plenty of parallels to be drawn between the UK in 1931 and in 2023, the latest of which is now the fact Blues have now won four straight against the Baggies.

Thanks for your company tonight. Do join us again from 12:15 tomorrow for another bumper instalment of Championship action.

What's that? You want MORE Championship derby action? Already? Cor, you don't want much, do you?

Ok, well, we can do it, but I'm afraid you'll have to wait until 12.15 tomorrow when we'll be back right here to bring you live coverage of Sunderland v Middlesbrough.

Probably worth sticking around afterwards to keep up to date with leaders Leicester, Ipswich and Preston, struggling Sheffield Wednesday, Rotherham and QPR, and everyone inbetween too.

You know you'll miss it all terribly during the international break.

The Albion fans will still be seething for a long time after this - and those present were sent on their way home by some typically unkind farewell chants from the Tilton End.

But the home supporters certainly are not bothered as they cheer their side off to the backdrop of UB40.

Seven goals in four nights at St Andrew's now.

After having gone six games without a win prior to that, John Eustace's side have turned another corner again - and the blue side of Birmingham is bouncing again.

And just like that, Blues are into the top-five while Albion slip two places to seventh on goal difference.

City are only four points ahead of 14th-placed Millwall, however.

The Championship, ladies and gentlemen.

Birmingham come from behind to secure a famous win - the first time they have done so in more than two years.

John Swift's fine early opener was soon forgotten as a hugely controversial penalty, awarded by James Linnington against Cedric Kipre for a challenge on Koji Miyoshi, allowed Juninho Bacuna to level from the spot.

Former Wolves man Dion Sanderson, born in nearby Wednesfield, powered home a beautiful header to complete the turnaround before half-time.

Darnell Furlong somehow missed when it seemed easier to score the equaliser after the interval and Gary Gardner added salt to the wounds with a sublime free-kick into the top corner in the closing stages.

Birmingham have beaten West Brom for the fourth straight time, something they had not achieved in 92 years.

Alex Palmer is 50% cat. There is no other explanation. He has somehow clawed the ball off the line from Pipa's deflection from a right-wing cross when Blues seemed destined to score a fourth through an own-goal.

There will be six additional minutes.

Cedric Kipre glances on an in-swinging free-kick from Alex Mowatt harmlessly off-target. Albion running out of ideas.

More changes. Pipa is on for Darnell Furlong who really should have put Albion on level terms in this second half.

Juninho Bacuna is off for Blues, as is Jay Stansfield. Scott Hogan, hat-trick hero last season at The Hawthorns, comes on with Gary Gardner.

Juninho Bacuna is having some game. He wriggles his way out of trouble past three Albion players in his own left back position and then launches a cross-field ball towards Oliver Burke which draws Alex Pamer out of his area to hack clear.

Siriki Dembele is withdrawn by John Eustace with big striker Lukas Jutkiewicz coming on for the final 20 minutes or so.

And a huge blow for Albion as goalscorer John Swift goes down on his haunches and is unable to continue. Perhaps a calf problem. Tom Fellows will replace him. Big shoes to fill.

West Brom's gloom deepens.

Another chance for Darnell Furlong, lurking at the far post to meet a deep cross swung in by Alex Mowatt.

Siriki Dembele does just enough to put him off as he plants his header straight into the breadbasket of John Ruddy from eight yards out.

Official confirmation that tonight's crowd - 21,495 - is Birmingham City's biggest since the Covid pandemic.

The last time they had this many in at St Andrew's was back on 22 February 2020, less than a month before the country went into lockdown.

But most of the regulars here look like they will be going home happy tonight, unlike the 1,978 Baggies fans who have crawled through the early evening traffic down the A41 from the Black Country.

And, when they get home and see the highlights, they'll be feeling even less happy!

Still time though...

Koji Miyoshi's race is run for tonight, he is replaced by Oliver Burke.... who used to play for Albion, narrative fans!

Miyoshi may prove to have had the biggest impact of all tonight, winning that penalty which changed the course of the game.

Albion keeper Alex Palmer produces one of the best punches you'll see to clear a Blues corner.

It's the final action before Carlos Corberan shuffles his pack. Okay Yokuslu and captain Jed Wallace go off with Nathaniel Chalobah and Brandon Thomas-Asante coming on for the Baggies. They have to go for it.

Darnell Furlong has his head in his hands. It should be 2-2.

Matt Phillips swings in an inviting deep cross from the left, Furlong ghosts in totally unmarked to slide in and meet the ball with a first time shot just yards out, only to skew his effort inches past the base of the far post.

Determined pressing from Blues, closing down at every opportunity, leads to Alex Palmer walloping the ball clean out of play.

They are working hard but will they be able to maintain these levels for another half-hour an change?

Goals aside, neither keeper has had much to do with their hands this evening.

Bitty start to the second half in truth. Albion seem set on playing quickly and pressing forward at every opportunity. A couple of corners have been overhit though, wastefully.

Blues will have to weather a storm at some point. Maybe this is a squall starting.

Cedric Kipre is furious once again, this time he slides in to Siriki Dembele who was bursting into the box, his challenge is timed to perfection and pokes the ball into Dembele's boot, only for the referee to award a corner.

Fortunately for Albion it comes to nothing.

Conor Townsend is on for Erik Pieters at the break for West Brom. Presumably a knock of some kind.

Looks like Matt Phillips will push forward and Albion will adopt four at the back in the second half after starting with three in the middle with wing-backs.

Wonder what the message from Carlos Corberan was while the Baggies players were munching on their orange slices?

Surely putting their sense of injustice to one side and trying to win the game afresh. They looked largely untroubled in those opening 20 minutes and John Swift's opener was a goal of class built upon a foundation of good fortune.

The players are heading back to the middle. Act 2 is about to begin...
