MoriMORI’s polls are routinely more variable than the other pollsters and the polling organisation’s latest survey – for today’s Sun – is more volatile than most.  It has certainly caused a large movement in ConservativeHome’s poll of polls – putting the LibDems above 20% for the first time since the fallout from Charles Kennedy’s resignation.

Whether the poll’s exact numbers are accurate the survey is in line with movements in other polls (as with yesterday’s ICM survey).  We are observing big falls in Labour support and we are seeing the LibDems – rather than the Tories – benefiting from Labour’s unpopularity.
