Clegg faces squeeze as Labour demands head-to-head debate between 'prospective prime ministers' Cameron and Miliband

Nick Clegg risks being shut out of TV debates ahead of the 2015 general election under Labour plans for a head-to-head battle between the only two men who can be Prime Minister. Labour said it wanted to see straight fight between David Cameron and Ed Miliband, in an apparent shift from previous demands for a re-run of the 2010 debates when Lib Dem Mr Clegg was also included.
