Coronation Street spoilers follow.

Coronation Street star Jack P Shepherd has revealed more about David Platt's reaction as the truth about Max Turner's stealing is exposed.

Last week, teacher Daniel Osbourne accused Max (Paddy Bever) of robbing his wallet following their recent clashes at school. When Max denied it, David backed him up.

In Monday night's double bill (September 27), Max pushes his luck too far by trying to use Daniel's bank card at the Corner Shop.

The card is declined and Dev Alahan (Jimmi Harkishin) soon warns David about this suspicious moment.

Although David is shocked to realise that Max really is a thief, he covers by making out that he lent his own card to Max and everything is fine. But will Daniel (Rob Mallard) find out what's going on?

Speaking about the scenes, Jack explained: "When David goes into Dev's shop and Dev says that Max was in there earlier with a credit card that got declined, that is the moment that David realises that Max has lied.

"But instead of going 'he's got Daniel's card', David makes an excuse and tells Dev that it was his card that he gave to Max for a pizza.

"It's all a bit suspicious and very bad parenting from David, because he now knows that Max has nicked the wallet but he sticks up for him saying he hasn't.

"David has already gone too far with the lie, so he can't back down and he can't retract it. He is now very worried that he is going to get caught out in this lie because he has let Max get away with it.

"Now David is in the wrong, because if anyone finds out that David has let Max get away with nicking the wallet, it is just as bad. Max taunts David and says: 'Well that's not going to look very good if anyone finds out that you knew about it!'"

Jack also discussed why David may be struggling so much with how to discipline Max.

He said: "It could be a combination of things. David feels like Max has been through a lot in his childhood. But also this is the first time that Max has been playing up, so at first David is quick to defend him because he believes that Max wouldn't nick Daniel's wallet.

"When David finds out he has, it is too embarrassing for David to say he has, so he hides it.

"David can also see a bit of himself in Max. When David used to play up and Gail was at the end of her tether with him, it was always Audrey that used to see the good in David.

"It would be interesting to see it come full circle. For example, if Max played up and David loses his temper, it would be nice for Gail to be the one to see the good in him. That would be an interesting dynamic."

Coronation Street airs tonight at 7.30pm and 8.30pm on ITV.
