When the time came, however, Tiririca pressed the wrong button on the computerized system and accidentally voted for an opposition proposal for a much bigger increase in the wage than the government wants, according to Brazilian media who spoke to his office. The leader of the opposition PSDB party in Congress' lower house, Duarte Nogueira, said he was grateful for the unexpected support, although the government still won the vote.

"I went and thanked him - after all, it's the support of the deputy who won the most votes in Brazil," he was quoted as saying by the Agencia Estado news agency.
