Poll position?

The BBC has been reporting an Ipsos-Mori poll showing Labour lagging the Liberal Democrats on the 25-27 September, not for the first time, as Anthony Wells points out. I have no wish to underestimate the challenge facing the party, but why did it not also report a more recent daily tracking poll from YouGov conducted on 27-28 September suggesting Labour is ten points ahead of the LibDems, having risen five points at the start of the conference? The BBC should either resume their former habit of ignoring polls, or avoid picking and choosing the ones that suit their narrative.
