LONDON, June 4 (Reuters) - Mexico's peso and South

Africa's rand both extended sharp selloffs on Tuesday following

the two countries' respective elections.

The peso was down nearly 1.5% to just shy of 18 to

the U.S. dollar as traders continue to fret about the

ramifications of a landslide victory for the Claudia

Sheinbaum-led Morena party and its allies in Sunday's election.

It took its drop in recent days to nearly 5% and means that

June is currently on track to be the peso's worst month since a

17% plunge at the start of the COVID-19 pandemic in March 2020.

South Africa's rand, which has also been hit by the prospect

of a potentially fraught coalition government after a poor

election showing from the ruling ANC party, fell 1.3% on

Tuesday to take its fall over the last week to around 3.5%.
