By Matt Chorley, Mailonline Political Editor PUBLISHED: 10:16 EST, 25 September 2012 | UPDATED: 03:30 EST, 26 September 2012 It seems there is only one must-have accessory at the Liberal Democrat conference in rainy Brighton: A badge declaring ‘I’m A PLEB!’ Hundreds of the novelty badges have been sold in the last 24 hours, inspired by Vince Cable’s declaration that he was a ‘pleb’ who could not resist a dig at Andrew Mitchell, who is under pressure over claims he used the four-letter word during a rant at Downing Street police. Senior Lib Dems think there is political capital to be gained from siding with the police – and the ‘plebs’ – in the big political division of the week.
