Mexicans vote in election overshadowed by violent attacks

Mexicans are going to the polls on Sunday in an election which is almost certain to see the country's first female president elected.

Both the front runner, Claudia Sheinbaum, and her main rival, Xóchitl Gálvez, are far ahead in the polls of the only male candidate, Jorge Álvarez Máynez.

Voters will also elect all members of Mexico's Congress and governors in eight states, as well as the head of Mexico City's government.
