Mexicans in new protest at Pena Nieto election victory
Thousands of protesters have been marching through the streets of Mexico City to protest against the official result of this month's presidential election.
The march was called by a new student movement, "Yo soy 132" (I am 132) which accuses the winner, Enrique Pena Nieto, of buying votes.
They also say he arranged favourable coverage from main television network, Televisa.
Mr Pena Nieto has rejected all charges.
"No to fraud," and "Out with Pena", shouted the protesters in this latest march against the result of the 1 July vote.
"Mexico wants a country that is honest and democratic," protester Marlem Munoz told the AP news agency.
The protest also attracted supporters of the runner up in the poll, left-wing candidate Andres Manuel Lopez Obrador, who has refused to accept the official result.
Mr Pena Nieto, from the Institutional Revolutionary Party, or PRI, was confirmed as the winner after a final recount, with 38.21% to Mr Lopez Obrador's 31.59%.
The electoral court has until early September to rule on the validity of the election and declare a president-elect.
Mr Pena Nieto said he hoped the other parties would respect the election result.
The PRI, which governed Mexico for 71 years until 2000, did not win a majority in congressional elections, also held on 1 July.
This means Mr Pena Nieto will probably need support from opposition parties to enact reforms in key sectors such as energy, tax and labour.
The new president is due to be sworn in on 1 December.
