Coronation Street viewers were furious with Sarah Platt while watching Thursday's show.

She was embroiled in a row with her estranged husband Adam Barlow, after he flirted with their neighbour, Alina Pop.

Furious Sarah made a comment about Adam's nationality, calling him a "stupid smug Scottish git".

She shouted at him: "You think you're so clever? You're not, you're a stupid smug, Scottish git."

Some viewers took offence to this and even accused the show of "casual racism".

One tweeted: "Well thats the Scottish audience switching off #casualracism."

Another complained: "You know that referring to someone's national origins as an insult or reason to deny something has been held to be racist, Sarah Platt?! #ScottishGit."

Adam was unbothered and mocked ex wife Sarah

"Corrie why did you need to include 'Scottish' in Sarah's rant? was 'Stupid, Smug, Git' not enough? Wonder how many more Scottish references you’re going to throw in #RacistCorrie," moaned a third.

"Scottish git, skatin on thin ice there Sarah," warned another.

Another added: "Oooh I think that was a bad decision with the Corrie script tonight.?

Sarah was mortified as a potential new client over heard her shouting

"Sarah calling Adam a smug Scottish Git is not cool, should have just stuck with a smug git".

Others applauded Sarah for giving Adam what for, and defended the show's use of the line.

One ranted: "So calling a Scottish person Scottish now is racist? F*****g get a grip, it undermines actual, real, offensive racism.

"Do these people get paid for making a career out of being offended! #Corrie ".

Another giggled: ”Stupid smug Scottish git.” funniest line I've heard in a soap in year's. #Corrie ".

"Stupid smug Scottish git! Has to be the best line, for a long while!" added a third.

MirrorOnline has contacted the show for comment.
