An experiment has found differences between the brains of progressives and conservatives.

Head scans of students at University College London, conducted by neuroscientist Geraint Rees, showed a "strong correlation" between thickness in two regions, the amygdala and the anterior cingulate, and political viewpoint.

Rees said he was "very surprised" by the finding because the experiment was a lighthearted item commissioned by Colin Firth for his guest-editing slot on BBC Radio 4's Today programme.

The actor has said he no longer supports the Lib Dems, and joked about Nick Clegg: "I think we should have him scanned."
