Big Brother 2012: Deana and Sara clash over politics!

Deana argue

An argument in the Big Brother house is no longer really news, but one about politics is certainly unusual!

After some of the recent slanging matches over chocolate and broccoli, rows over which political party people should be backing seem rather out of place.

But last night it set Sara and Deana off on a rather heated debate, as the Scot returned from the White Room after opting to press her buzzer and leave.

Sara was trying to explain to the other housemates how she comes to her decision which party to support, although was doing a brilliant impression of an MP by avoiding any questions.

First claiming she didn't want to reveal who she voted, Sara eventually revealed she backed the conservatives in the latest election, but Deana wasn't convinced by her reasoning.

The result was a rather tense debate...
