The latest poll from Imasen and published in La Republica was supposed to be published tomorrow, but it got leaked and so La Republica, on this page, has confirmed the numbers.
According to this poll, Ollanta Humala has a slight lead. We note that the newspaper in question supports the Ollanta Humala campaign (about the only serious paper to do so). Nevertheless, this is the first poll to give Ollanta a lead in the last couple of weeks, with the big live TV debate up tomorrow evening (that you out there in the world can watch of CNN's Spanish language service, CNN Expansion, so I understand).
It's going down to the wire, be in no doubt. By the way, separate from the normal IKN Weekly issue 108, subscribers will get a full report on the debate proceedings either late Sunday evening or before the bell Monday morning.
