Two leading presidential candidates will no longer be running in Peru’s election next month, as electoral court imposes ban.

Julio Guzman was banned following a technical glitch during the registration for his candidacy. The court also rejected businessman Cesar Acuna for giving out cash during the election campaign.

In recent polls, Guzman was second presidential candidate to front-runner Keiko Fujimori ( daughter of former President Alberto Fujimori). He seemed to be a biggest rival for Fujimori. Acuna was at fourth place.

The recent poll reflects that Fujimori would secure 35% support, with Guzman 16% and Acuna with more than 3%.However, a candidate would need to have 50% support in the first round. If no candidate gets 50%, then the run-off would be scheduled on June 5.

On Wednesday, Guzman’s Todos Por el Perú party is believed to have violated the electoral rules for candidates.

“We are really stunned by this decision. We consider it totally unjust,” said party spokesman Daniel Mora after the ruling.

Earlier, Guzman had said he would call a mass protest if the electoral court ban him from the April 10 elections. He also called for ban on four candidates over non-compliance of electoral rules.

“If their cases are not treated with the same criteria, the current election and potential elected authorities will be illegitimate,” Guzman said in a report by Reuters.

Acuna’s ban came after a television channel revealed that the candidate handed out money to stall holders and a disabled man in a street market. But he said that it was a “humanitarian aid” to poor voters. He is running under the flagship of the Alliance for Progress party.

In January, Acuna came under scrutiny over “plagiarism” charges. He was accused of copying work in his 2009 doctoral thesis on education.

BBC reports that two candidates can still make an appeal to the court. However, analysts say that there are less chances that the court will overturn the rule.

The winner will replace President Ollanta Humala as he wraps up his five-year term.
