Well... this is awkward.
The Irish language can be tough - but thinking a political party is actually a leader's name is a basically a massive fail.
Just to clarify - Sinn Fein is a major Irish nationalist political party, and not a single person named 'Sinn Fein'. They also definitely are not the DUP.
Irish journalist Aoife Grace Moore, who is living in Oz, was quick to spot this error from Sky News Australia and highlight it via her Twitter account:

The article they shared featured an image of Gerry Adams, the fact that he's also now a member of the DUP is quite interesting too:
"Democratic Unionist Party's Sinn Féin says he will oppose any deal with UK Prime Minister Theresa May that undermines a 1998 peace deal."
Again, we must reiterate, we KNOW that people make mistakes. That doesn't stop the hilarity from ensuing online:

A positive thing to come out of this blunder is that it looks like the journalist in question could get a job out of it!

Fair play Aoife!
