SAO PAULO (Reuters) - Right-wing Brazilian presidential candidate pledged to slash the size of the state, reduce payroll taxes and privatize many state companies in remarks celebrating his commanding lead over leftist rival Fernando Haddad in Sunday’s first-round vote.

In a video streamed live over social media with economic advisor Paulo Guedes sitting by his side, Bolsonaro, who will face Haddad in an Oct. 28 runoff vote, said he would have clinched the race with a majority of votes on Sunday if it were not for faulty voting machines.
