For Labour, last week’s drama was a parable of what Ed Miliband regards as Cameron’s fatal flaw – an obsession with politicking, an absence of conviction, a head full of stratagems. But the Labour leader himself is not above a few stratagems – one of which is to detach Clegg from Cameron. Gone are the days of the AV referendum campaign when Miliband would not share a platform with the Lib Dem leader. On Friday, one of Clegg’s staff was in Miliband’s offices working against the clock on an amendment for tomorrow. Indeed, the apparent cosiness of the past week has been so great that Ed’s allies are dismissing the inevitable prophecies of Lib-Lab pacts to come. They are loath to give the impression that they are fighting for anything less than an outright Commons majority in 2015.
