Big Brother housemate Caroline Wharram was called to the Diary Room this afternoon where she was set a secret mission…

She must convince two of her fellow housemates that she is related to the Royal family. As part of her mission, she has to choose which two housemates she thought were most likely to believe her…

If she succeeds in convincing them that she does in fact have blue blood, she will win a high tea – including sandwiches and cakes – for herself and the two housemates she’s chosen.

If she doesn’t succeed… well, nothing happens other than she won’t have a cream tea…

We will of course keep you posted on what happens, but if it were me, I’d go for Sara, given that she’s an ardent fan of the Royal family, the Queen especially, and I’d tell her that I couldn’t tell her before because Big Brother had banned me from mentioning my Royal connections.

How would you go about this secret mission? And who do you think she should – or will – choose?
