Iran Press/ America: Castillo, an elementary school teacher seeking to implement new taxes and royalties on the mining sector, obtained 44.8% support in the survey of the Institute of Peruvian Studies (IEP), while Fujimori, a business-friendly conservative, netted 34.4%, Reuters reported.
The poll of 1,208 people was conducted for Peru's La Republica newspaper on May 20-21 and had a margin of error of 2.8 percentage points.
Castillo, who had begun to flounder in polls earlier in May, has gained significant ground since the same IEP survey in mid-May. He obtained 36.5% among intended voters and Fujimori 29.6%.
On Saturday, protesters marched in Lima and other major Peruvian cities toting banners and shouting the slogan "Fujimori never again." Fujimori's father, the former president Alberto Fujimori, is in prison over corruption charges.
Castillo, who stormed into the run-off with Fujimori following a win in a shock first-round election, strongly supports Peru´s largely poor, interior rural communities. Market watchers, however, view his candidacy as a potential threat to the industry in the world´s No.2 copper producer.
The Sunday poll also indicated that 13% intend to vote blank or annul their vote in the June 6 ballot, while 5.1% were still undecided.
