It’s the eve of the referendum, so we have a flurry of late polls. Later on this evening we will have figures from ComRes and YouGov (Ipsos MORI’s final poll is normally in the Standard, so will probably be out tomorrow morning), already we have final figures from TNS and Opinium.
Opinium have topline figures of REMAIN 44%, LEAVE 45%, Undecided 9%. Leave are ahead by the tiniest of margins, but clearly the two sides are within the margin of error of each other. Full tabs are here.
TNS‘s final referendum poll also has Leave ahead, this time by two points. Topline figures here are REMAIN 41%, LEAVE 43%, Undecided or won’t vote 16%. Note that unlike TNS’s last few polls their headline figures here are NOT weighted for turnout – with their turnout model they would have been Remain 42%, Leave 49%. Full tabs are here.
I will update later once ComRes and YouGov publish. In the meantime both of the non-British Polling Council companies who produced more unorthodox polls last week have produced updated figures – SurveyMonkey have final figures of REMAIN 50%, LEAVE 47%; Qriously (the company sampling via smartphone ads) has final figures of REMAIN 37%, LEAVE 51, Don’t know 12%. Again, make of that what you will.
UPDATE: The ComRes and YouGov eve-of-referendum polls are now also out. Whereas TNS and Opinium both had Leave leads, ComRes and YouGov both show Remain ahead (albeit, by different margins):
ComRes for the Daily Mail have topline figures of REMAIN 54%, LEAVE 46%, a widening of the Remain lead after their last poll showing Remain and Leave within a point of each other. ComRes have reallocated don’t knows based on respondents’ views of the impact of Brexit on the economy, which looks like it boosted Remain by a point or so. Full tabs are here.
YouGov for the Times have topline figures of REMAIN 51%, LEAVE 49% – so considerably closer. The YouGov poll now includes a turnout weight (though it made no difference at all to the topline) and a squeeze question, which also bumped Remain up by a point. Full tables are here. On YouGov’s website they’ve also updated the multilevel regression and post-stratification (MRP) model of referendum voting using all their data, which they first posted earlier in the week, that is now also pointing towards a small lead for Remain.
Note that all four of the polls here include Northern Ireland. Most general election polls don’t, and so polls during the EU campaign have varied on whether they do or do not include NI – all these four do.
UPDATE2: Two more polls published on the day itself. Note that these polls were conducted before polls opened, they are only published today. It’s illegal to publish polls conducted on the day until polls close, but perfectly fine to publish polls conducted before polls opened.
Ipsos MORI‘s final poll has topline figures of REMAIN 52%, LEAVE 48%, putting Remain back ahead after a leave lead in MORI’s penultimate poll. MORI have slightly changed their turnout filter for their final poll, basing it on how likely people say they are to vote and how important they say the result is to them. Full tabs are here.
Finally, and a little surprisingly, Populus have produced a final call poll. Populus’s Andrew Cooper has been working with the StrongerIn campaign so the company haven’t been putting out regular polls during the campaign, but they have produced final topline figures of REMAIN 55%, LEAVE 45%. Unexpectedly given the topline results the poll was conducted online (completely messing up that “phone & YouGov saying in, other online saying out” pattern). Populus haven’t released tables yet, so I’ve no details of the weightings or adjustments used.
