Brexit Bills and latest voting intention
I've got an article over on the YouGov website about the difficulty on polling on the Brexit financial settlement (or "Brexit divorce bill" as the more Eurosceptic elements of the press tend to call it). Brexit is obviously a very complicated issue - the Brexit deal will almost inevitably dominate the next year of British politics, yet the complexities of it mean it's very hard to ask about until there's actually a deal on the table.
The financial settlement between Britain and the EU should, on the face of it, be one of the more simple issues. On the face of it you might expect it to be fairly simple to ask people what sort of financial settlement the public would think was reasonable and what sort of settlement would have the public thinking Theresa May has struck a poor deal. In fact such questions give us a very poor guide, simply because most people are not particularly good at comprehending very large numbers.
If you ask a question about what a reasonable price is for, for example, a pair of shoes, it should work very well. Everyone knows roughly what shoes cost, and know the value of £10 or £30 or £100. The same does not apply for government spending - £50 billion is an unfathomably large amount of money... but then, so is £20 billion, or £10 billion or £5 billion. Most of us don't really have any good yardstick for judging just how big or small these huge numbers are, nor whether they are a good or bad deal for Britain.
Nevertheless, if you ask people about a financial settlement people will still express opinions. Back in August there was an ICM/Guardian poll that found 41% of people though a £10bn settlement would be acceptable, up from just 15% in April. This seemed like a startling rise, but as both ICM and the Guardian cautioned, it could just be the way the question was worded. In April ICM first asked about the lower figure of £3bn, but in August £10bn was the lowest they offered.
This seemed like a more plausible explanation to me, but just to be sure we tested it at YouGov. We used a split sample - one half of the respondents got a grid of three questions asking about settlements of £5bn, £10bn and £20bn. The other half of the sample got a grid of three questions asking about settlements of £25bn, £50bn and £75bn.
On the first bank of questions 38% thought £5bn would be acceptable, 18% thought £10bn would be acceptable, 11% thought that £20bn would be acceptable. Looking at the other half of the sample, 29% thought that £25bn was acceptable, 9% thought that £50bn was acceptable, 6% thought that £75bn would be acceptable (full tabs are here.)
Taken as a whole we get the the rather perverse finding that while support generally falls as the size of the settlement increases, £25 billion is far more acceptable to the public than £20 billion. This is nonsense of course, and the reason is simple enough - people take their cues from the question itself. In the first half of the sample, £5bn was the lowest amount asked about, £20bn the largest amount, and many respondents presumably took this as an implication that £5bn was a low settlement, £20bn a high one. For the second half of the sample £25bn was the lowest figure asked about, so many respondents presumably took the implication that this was a low settlement. Whether people said a sum was acceptable or not was less about the actual number, more about whether the question implied that it was a low or high figure.
The point is that questions about what level of "divorce bill" will be acceptable to the public don't really tell us much. People don't have any good way of telling what is a good or bad deal and are really just expressing their unsurprising preference for a smaller settlement. When (or if) Britain and the EU do finally agree on a sum, it won't be so much the particular figure that determines whether the public see it as a victory or a sell-out, but whether the media and political class present it to them as a good or bad deal.
Meanwhile, lastest GB voting intention figures this week are below - both show the parties pretty much neck-and-neck, neither show any obvious movement: YouGov/Times (12th-13th Sept) - CON 41%(nc), LAB 42%(nc), LDEM 7%(+1), UKIP 3%(-1) (tabs) ICM/Guardian (8th-10th Sept) - CON 42%(nc), LAB 42%(nc), LDEM 7%(nc), UKIP 4%(+1) (tabs)
