In a terrific year for comedy at the Fringe, the winners of the 2010 Foster's Edinburgh Comedy Awards (formerly the Perriers) are Russell Kane, Roisin Conaty and Bo Burnham. The prizes - cheques for £10,000, £5,000 and £5,000 - were presented to the three comedians on Saturday in the Spiegel Tent in George Square in a celebration of 30 years of these awards.
