BIG Brother fans have been left scratching their heads after Sarah Griffiths made a huge faux pas during the latest task.
In a bid for the contestants to win luxury shopping items, the BB house has been transformed into Downing Street.
The housemates have been divided up into Government roles, with Khaled being named Prime Minister, Emma made Minister of Transport, Daze as Minister for Energy and Nathan given the job Minister for Agriculture.
A mock set of Number 10 Downing Street has even been installed in the BB house, which leads to the Government's 'offices' away from the remaining contestants.
But as the task got underway, Sarah made a huge gaffe as she repeatedly banged on the door of Number 10.
Highlighting to the nation that she doesn't know who the UK's Prime Minister is, the farmer shouted: "Rishi...Rishi...Rishi....Rishi!

"Stop making the pensioners pay more, they're going to freeze to death!"
Rishi Sunak has not been Prime Minister for more than three months, following the 2024 General Election. Keir Starmer is now PM.
Sarah was joined by fellow housemate Izaaz at the door and he failed to correct her mistake.
Big Brother fans couldn't believe their ears and rushed to X, formerly known as Twitter, to share their astonishment.

One exclaimed: "Do they still think Rishi is Prime Minister?!"
Another added: "Rishi?? He hasn’t been prime minister for months now loool."
A third penned "Does Sarah know that Rishi’s not the PM anymore??"
And someone else added: "Can someone tell Sarah Rishi Sunak isn’t the Prime Minister anymore!"
Meanwhile, a huge row erupted during the Big Brother Government task - over a bagel.
Dean threw one of the Minsters' leftover lunchtime bagels in the kitchen bin to avoid anyone eating it and losing the task.
Emma briefly questioned his decision - before Izaaz began telling housemates she was "upset" over it.
An almighty argument blew up, with a furious Dean branding Izaaz a "sh** stirrer".
