MEXICO CITY (Reuters) - Mexico's three leading presidential candidates have not declared a single peso in direct private financial contributions to their election campaigns, federal records show, raising concerns from corruption watchdogs about the potential influence of dark money in a pivotal contest.
Candidates from Mexico's three main political parties said they have relied almost exclusively on money from their parties, which is overwhelmingly public, to bankroll their campaigns, a total of more than 634 million pesos (24.5 million pounds).
