EDIT 2: THIS IS NOW CONFIRMED, WE HAVE THE OFFICIAL IPSOS PUBLICATION, SEE UPDATE 2 BELOW --> A little background is needed first. In Peru surveys are not allowed to be published in the week before an election, but survey companies can go out and take polls and then "publish them to foreign sources". Which means in effect the pollsters can get round an out-dated law. So here's a screenshot of what's reportedly a poll taken by IPSOS and supposedly published today (and here's a Peru website carrying the same screenshot):
UPDATE: GFK has it at PPK 51.1% and Keiko 48.9% in a poll published today Saturday. Reuters link here, here's the paydirt:
"Kuczynski won 51.1 percent of valid votes in a mock voting exercise GfK conducted on Saturday, compared to Fujimori's 48.9 percent. The survey had a 1.6 point margin of error, up or down."
UPDATE 2: Here's the screenshot of the official IPSOS PDF publication, out this afternoon:
