PROF CURTICE AND THE POLL DATA MYSTERY

Professor John Curtice has a comment piece on the WhatUKthinks website (HERE) with the title: Is there a new geography of Brexit?  It's about the  analysis of YouGov polling data released by the anti-Brexit Best for Britain campaign and first reported by The Observer that I posted about (HERE), which used the regression techniques of FocalData.

He is looking at the polling data in connection with the Labour party's position on Brexit, but he says this:

"The data were reported as showing that support for Remain across the country as a whole now stands at 53%, while support for Leave was estimated to be 47% (which, indeed, were the figures that had been previously been published for the People’s Vote poll in particular). That, of course, represents a five-point swing from Leave to Remain as compared with the result of the 2016 referendum, when Leave won 52% and Remain 48%. But it is more or less in line with other polling conducted during the last three months which, on average has put Remain on 52%, Leave 48%. So there is no evidence in these numbers of a significant new swing to Remain. Rather it simply represents confirmation of other recent polling that Remain appear to be slightly ahead".

Which is all very encouraging, but I noted he didn't refer to the ComRes poll, also of 10,000 people but only in leave voting constituencies that returned Labour MPs in 2017. This shows a majority (of the 10,000) would now vote 51.6% for REMAIN.  But in looking at the ComRes website again I notice the poll data has mysteriously lost 16 pages. The index and pages 83-95 have disappeared. Page 91 showed in 2016 the same voters were 51.7% for LEAVE. I posted about the original data HERE with a link to the first - complete - version of the polling data.

I have no idea why the pages have been removed. Interesting though isn't it?  Why would they do that?
