Polls in the last week had been consistent in showing a small decrease in Conservative support and a small increase in Labour support, marginally reducing the Tory lead. While these polls aren’t quite so uniform (Deltapoll show the lead steady, ComRes shows movement in the other direction… though if you consider ComRes carry out two polls a week, their lead compared to a week ago is actually unchanged), most still show movement in Labour’s favour.
There remains a significant difference in the overall size of the lead, varying from just six points in the BMG poll to fifteen from Opinium. It is hard to put a specific figure on what sort of lead the Conservatives need to secure an overall majority – it obviously depends on exactly where they gain or lose votes – but as a rough rule of thumb it is probably somewhere around six or seven points. That means at the moment the vast majority of polls are still indicating a Tory majority, but there is no longer that much room for further tightening.
