The current humanitarian crisis is making a Yes vote less certainby Peter Kellner / September 4, 2015 / Leave a comment
Until a few weeks ago, I thought that it was at least 90 per cent certain that the UK would vote in the coming referendum to remain a member of the European Union. YouGov polls this year had shown a consistent, if modest, lead for staying in rather than leaving. Typically, the balance was around 45-35 per cent for staying in rather than leaving, with the rest saying “don’t know”. With the fear-factor likely to intensify as polling day approaches, and some voters in the end wanting to avoid the risks of Brexit, we were set for a comfortable majority for sustaining our membership of the EU.
The last few weeks have changed the odds. I still think a vote to stay in is more likely than a vote to leave; but instead of being 90 per cent sure of the outcome, I am now only 60 per cent sure. Whereas before, I thought it would take a bolt from the blue to change the outcome, I can now envisage the scenario that results in Brexit.
This is partly because YouGov’s latest survey puts the lead for staying in the EU at just two points, the lowest since January. Statistically, the two sides are now level-pegging. On its own, this does not change the outlook: there was always likely to be the occasional blip in the polling numbers. Rather, it’s the reason behind our latest figures that should worry pro-Europeans, alongside a second factor that has yet to come into play: the possibility that Jeremy Corbyn will either campaign for Brexit or play an equivocal role, allowing, and perhaps encouraging, left-wingers in the party and the unions to do so.
