ComRes also showing boost for others
The figures for ComRes's poll for the Independent on Sunday are out, and show topline figures (with changes from their last poll at the end of April) of CON 40%(-5), LAB 21%(-5), LDEM 18%(nc). Others enjoy the same sort of boost as in BPIX, which includes UKIP at 5%, Greens at 4% and the BNP at 3%.
John Rentoul's report also says "Our poll also suggests that the minor parties are set to break records in the European elections next month" but I think he is referring to a question that found 43% agreeing that they were likely to vote for minor parties, rather than a proper European voting intention question.
