Thanks for joining us this afternoon, stay tuned for a full match report and all the best reaction from Wembley on a memorable afternoon for the Bantams.
Congratulations to Bradford who climb out of League Two for the first time in seven seasons. Their victory was built on a devastating first-half display when they roared into a 3-0 lead.
Harding goes for goal and finally has Northampton's first shot on target, but McLaughlin claims with ease.
Northampton win a free kick just outside the Bradford box on the right. Time for a consolation, perhaps.
Guttridge goes for the spectacular from Widdowson's cross but sends the ball in the wrong direction.
Tozer's throw is headed out and O'Donovan's return header goes wide of the goal, with Northampton yet to have an effort on target.
Wells makes way for Bradford, to a deserved standing ovation from the Bantams fans, with Connell coming on. Northampton waste their free-kick.
Akinfenwa heads the corner away from in front of Nicholls, with Bradford not really making too much effort to challenge.
First touch for Atkinson as he puts the ball out for a throw, with Tozer's long ball going over Akinfenwa before Clarke's header goes well wide.
Guttridge's ball into Harding is taken well on his chest but he fires well over the bar from outside the box.
A lone supporter is on his feet in the Northampton end trying to urge his side on and encourage his fellow fans, but there's not much interest.
Bizarre scenes as Guttridge is given some instructions on paper which he takes a look at before tucking them into his shorts. Never seen that before.
Demontagnac is penalised for a push on Darby at the far post as another Northampton attack comes to nothing.
Neat build-up play from Bradford sees them cut through Northampton as Reid and Meredith combine to set up Wells, but his low shot from the edge of the area lacks the necessary power.
Reid is close to making it 4-0 as he volleys wide after arriving unmarked at the far post onto Wells' deep cross.
Akinfenwa fires well wide on the turn from eight yards after Hackett's short free-kick to Harding is drilled into the box.
Bradford cut out another Northampton attack and Thompson embarks on a run which takes him all the way to the edge of the opposition box before dragging his shot wide of the target.
There is not the same intensity to the second half from Bradford, but having opened up such significant lead, that is understandable.
Long ball forward towards Akinfenwa but Davies gets there first and his header goes back to McLaughlin.
The Bradford fans rise as one to salute and pay tribute to the 56 supporters who died in the Valley Parade fire of 1985.
First change for Northampton with Collins coming off for Widdowson, while Akinfenwa will be on soon, too.
Demontagnac puts the ball out before Meredith's long throw into the box loops goalwards after coming off Hanson as Carlisle tried to clear, with Nicholls clawing the ball away.
McLaughlin races from his area to deal with a long ball down field, clearing his lines but also taking out O'Donovan and leaving the Northampton man in a heap on the turf.
Another ball is aimed in towards Platt but he cannot get his header on target with McLaughlin in no-man's land.
Bradford get the second half under way. No changes from either side, perhaps a surprise from a Northampton point of view, given how poor they were.
We're back for the second half, can Northampton find a way back into this contest, or are Bradford already bound for League One?
It is a long way back into this contest for Northampton. They have been second best in every single department so far and need to buck their ideas up to avoid being humiliated.
Referee Stroud brings the half to a close. Bradford have been excellent and fully deserve their lead, while Northampton's defensive frailties have been fully exposed.
Thompson is down on the turf with the trainer on. Doesn't look too good for the Bradford man, with his ankle seemingly the problem.
Awful pass by Doyle allows Northampton to put a deep ball into the box, but O'Donovan's far post header is claimed by McLaughlin.
Free-kick to Northampton in a decent position on the left corner of the Bradford box, about 10 yards out.
Wells looks to trick his way through the Northampton defence but Carlisle stands in his way once again.
Wells gets in behind the Northampton defence but Carlisle puts in a good tackle just as he prepares to shoot.
Reid's resulting corner is headed away and the second ball goes all the way through to Nicholls. Northampton need to get to half-time without conceding again.
It's nearly 4-0 to Bradford as Darby's long throw goes all the way across the box, is allowed to bounce and Reid's header on goal is well tipped over by a furious Nicholls.
Awful defending from Northampton as they allow another deep cross to reach Thompson, he heads it back across goal and Wells arrives to blast the ball home beyond a helpess Nicholls.
Bradford's dominance is demonstrated by the stats - they've had five shots so far, three on target, while Northampton are yet to even have an attempt on goal.
Good pressure from Bradford as they pass the ball around outside the Northampton box before Reid's cross is headed away and then Wells fails to connect properly with a shot from the edge.
Hanson is penalised for a foul on Cameron. Northampton are in danger of being overrun here and need to find a way back into the game.
Jones and Reid work a short corner, with the latter's cross too deep, but once again Bradford are first to react and Doyle's ball back into the box is headed home at the near post by McArdle as he gets away from his man.
Quick stat for you as Northampton try to recover - the side scoring first has won the last four League Two play-off finals, with the last side to win after conceding first Stockport v Rochdale in 2008.
Great header from Hanson to put Bradford in the lead. Wells' superb touch sent Reid away down the left and he cut back before feeding Meredith. The full-back's initial cross was too high for Hanson, but Thompson collected the ball and stood up a superb cross to the back post for Hanson to guide a superb finish over the flailing Nicholls.
Tozer has another chance to hurl a long throw into the box, but Stroud spots some pushing and Bradford have a free-kick.
Bradford have bossed the possession in the opening stages, but there is a real frenetic feel to the fixture so far, with both teams looking to go long at almost every opportunity.
Collins attempts a through-ball to his forwards but overhits the pass and McLaughlin gathers with ease.
O'Donovan is penalised for a high boot as he looks to break clear and Bradford have a free-kick on the edge of their own box.
Scramble in the Northampton box and it takes a last-ditch tackle to deny Wells as he looks to pull the trigger, before the Cobblers clear.
Referee Stroud halts play as Ben Harding has taken a nasty blow to the head as he challenged for the ball and has blood pouring down his face.
Tozer's throw is an absolute monster which goes all the way through to the far post and McLaughlin fists away.
Reid plays it short to Jones, whose good cross to the far post is headed over by Wells, who cannot get over the ball enough.
Wells takes responsibility but curls his effort over the wall and also well over Nicholls' crossbar.
Hanson is fouled by Cameron and and Bradford have a free-kick in a central position about 10 yards outside the box.
Couple of early touches for Bradford keeper McLaughlin as he gathers an over-hit through-ball and then a launched clearance from the Northampton defence.
The two teams are out on the pitch at Wembley ready for the pre-match formalities, with kick-off now just five minutes away.
The two teams have met four times already this season, with Bradford edging the two League Two meetings 1-0, while their FA Cup encounter went to a replay, with the Bantams then triumphing on penalties.
Our friends at Sky Bet have a host of markets available on today's game, but the main options are Bradford available as 6/5 favourites, Northampton on offer at 5/2 and the draw a 9/4 shot.
Northampton boss Aidy Boothroyd has preferred Clive Platt up front to Adebayo Akinfenwa, with the burly striker, who has not scored in his last 14 games, having to settle for a place on the bench.
First in touch is Chris Green from Huddersfield, who writes: "I'm a Huddersfield Town fan and I would like to wish Bradford the very best of luck ahead of today's play-off final. This will be a tough one for Bradford because Northampton have some good players, but I don't think they'll have any problem here if they perform to their potential and take their chances."
Northampton team: Nicholls, Tozer, Carlisle, Cameron, Collins, Hackett, Harding, Guttridge, Demontagnac, O'Donovan, Platt. Subs: Snedker, Johnson, Widdowson, Langmead, Akinfenwa, Robinson, Hornby
