Remember the last time you made a mammoth mistake in work and were forced to cover your face in shame as the rest of the world pointed and laughed?

Yeah, us neither, but that's because we're not the Australian news reporter who unwittingly revealed that they may need to brush up on their knowledge on political relations between the UK and Ireland.

In a tweet which has unsurprisingly gone viral, a reporter for Sky News Australia confirmed that not only did they think Sinn Féin was an actual person, but that he was also a member of the DUP.

Accompanying an image of Gerry Adams was a caption which read: "Democratic Unionist Party's Sinn Fein says he wil oppose any deal with UK Prime Minister Theresa May that undermines a 1998 peace deal."

And Twitter has obviously gone into meltdown.

"I'm a Northern Ireland native journalist and can't find full time paid work, but someone at Sky News Australia thinks Sinn Fein is a person," wrote Twitter user Aoife-Grace Moore.

Responding to that remark, one user joked: "When Sinn Fein hears about this, he will be livid" while another added: "I think it's short for Sinn Feinstein, and he's an old mate of Dee Youpee," 

And yep, the tweet has since been deleted.
