Ipsos MORI/Standard - CON 34, LAB 37, LD 10, UKIP 11

With the average Labour lead across the different polling companies now around six points, Ipsos MORI's monthly political monitor for the Standard had been showing some of their bigger leads - the last two polls both showed Labour's lead still in double figures. This month's poll brings that down, with topline figures of CON 34%(+4), LAB 37%(-3), LDEM 10%(nc), UKIP 11%(nc). While this brings MORI more into line with figures from some other companies, it's worth noting that a lot of the narrowing is down to likelihood to vote.

Economic optimism continues to grow, with net optimism now up to plus 23, from plus 20 a month ago (and as low as minus 30 if you go back to March).

According to MORI's analysis here Ed Miliband has hit his worst ever approval rating, with a net score of minus 36 (which they compare to William Hague and IDS's worst scores, minus 37). David Cameron's own approval rating was minus 20, Nick Clegg's minus 40, Nigel Farage's minus 7 (but with 35% don't know).

MORI also asked about whether several positive or negative attributes applied to each leader, showing the usual patterns of strength and weakness - Cameron has a strong lead on being seen as a capable leader (53% to Miliband's 28%), being good in a crisis (47% to 20%), having a lot of personality (40% to 19%) and a smaller lead on having sound judgement (40% to 32%). The two men were virtually tied on understanding the problems of Britain, and Cameron was seen more negatively than Miliband on being in touch with ordinary people and looking after some sections of society more than others.
