Pre-election protests in Mexico as ex-mayor joins presidential race

Mexico City ex-mayor Claudia Sheinbaum officially entered the presidential race on Sunday.

Mexico's electoral commission said it had received the registration of Sheinbaum, a member of Lopez Obrador's ruling Morena party and the favorite, according to polls, to win the June election. 

She was a spokesperson for  President of Mexico Lopez Obrador during his failed 2006 election bid, and served as Mexico City mayor from 2018 until earlier this year when she stepped down to run for president.
