One of the most interesting figures in the latest Populus poll in The Times is that over half the electorate think that neither Mr Brown nor Mr Cameron know what to do about Britain's economic problems.
Not surprisingly, it's the Lib Dems and other minor parties who have been the main beneficiaries of the slump in Labour support. They now account for 30 per cent of voter preferences.
Labour has dropped back five percentage points in a month to 28 per cent. It's not as bad as last summer, but as the reality of the recession bites, the Brown bounce has deflated.
