".....research carried out as part of the Party Members Project funded by the Economic and Social Research Council and shared exclusively with the Guardian...showing that 87% [of party members] voted remain" [Guardian, July 17]

Two surveys, two slightly different numbers, Nige. I wouldn't lie to you, honest. The point I used the figure for stands. Very rude of you to put "fact" in speech marks when what I told you was eminently checkable. Next time, check properly before you decide to get all nasty.

I did check, and couldn't find anyone claiming 90% (apart from you).
The claim is still highly unlikely. You are quoting a survey (or two) where you previously appeared to be quoting statistics which are not available, as it was a secret ballot.
Cross correlation with 'membership' of the Labour party would make it doubly difficult to find an accurate figure.
The percentages may well match up with what people claimed were their voting intentions previously, but those figures were proved wrong.

At some time you will have to accept that people mislead pollsters, either accidentally or deliberately.
Your original quote Ninety percent of Labour Party members voted remain. cannot be backed up in any reasonable way.
