In what ought to be a massive worry for Remain campaigners, public opinion has taken a significant shift towards a Brexit over the past week. These phone polls are the fifth and sixth released this week to show a lead for the Leave campaign.
Even among all Ipsos MORI participants - not just those who are certain to vote on June 23 - Leave had a two-point lead (51/49%). This is important because even when Remain has been behind with those who are certain to vote in past polls it has usually still been in the lead among all respondents.
These are also the latest surveys conducted over the phone to give leads to Leave after months of phone polls consistently indicating leads for Remain.
Importantly, both pollsters were some of the most accurate when it came to predicting the outcome of the Scottish independence referendum.
This is what Ipsos MORI and Survation's latest surveys means for Business Insider's live EU referendum opinion polls chart. As the chart illustrates, public backing for a Brexit has surged over the past week.

As Business Insider said earlier this week, this pro-Brexit swing is not a blip. It is a very real statistical phenomenon and it couldn't come at a worse time for David Cameron and co with just one week until the referendum.
A swing is taking place in the EU referendum betting market, too. After months of Remain being the overwhelming favourite, William Hill estimated earlier this week that Leave will be the most likely outcome by the weekend.
More opinion polls are expected to be published this week by ComRes and Opinium.
