The prime minister, Scott Morrison, has been forced to remove a seemingly innocuous Instagram post after being pranked by a couple of Queensland radio DJs.

Morrison was touring far-north Queensland when he agreed to appear on Cairns radio show Hit103.5 owned by ARN.

The PM was interviewed by the network’s breakfast team of Shad and Carly and post-interview posed for a photo with the pair that he later posted to social media.

However, keen-eyed fans of ScoMo’s social media were quick to spot the mug held by Shad featured the word “c*nt” and the post was swiftly deleted.

Not so Shad, who clearly thought his unsavoury coffee receptacle was hilarious and re-posted the image to his very own Instagram account. ARN has not commented on the prank.
