EMERGING MARKETS-Politics weigh on Chile, Brazil stocks, inflation in Mexico

(Updates with final prices, details from Mexico)

SAO PAULO, Nov 23 (Reuters) - Equities markets across Latin

America fell on Thursday amid light Thanksgiving trading, led by

the blue-chip IPSA index in Chile (Stuttgart: 704599.SG - news) , where investors are still

jittery over a weak performance by conservatives in elections

over the weekend.

On Thursday leftist Chilean presidential candidate Alejandro

Guillier, competing in a run-off after coming second in a first

round on Sunday, said he was open to eliminating Chile's

quasi-private pension fund system for a state-run model.

Additionally, workers at BHP Billiton Ltd's

major Escondida copper mine in Chile walked off the job

temporarily, spooking investors in the mining-dependent

country. The IPSA closed down 1.84 percent.

In Mexico, the S&P/BVM IPC index slipped by 0.13

percent after data showed a surprise acceleration in inflation

in early November, complicating the central bank's hopes of

dampening price pressures before the end of 2017.

Shares (Berlin: DI6.BE - news) in miner Grupo Mexico put downward

pressure on the stock index, slipping 2.08 percent.

Brazil's Bovespa dipped 0.04 percent as President

Michel Temer continues to face difficulties pushing through a

pension reform seen as key to shoring up fiscal health.

On Wednesday night, the congressman in charge of drafting

the reform presented a new version in an event at Temer's

official residence. However, attendance was poorer that

expected, which some analysts interpreted as a sign of

relatively weak support for the measure.

Among the poorly performing major constituents of the index

was steelmaker Usinas Siderurgicas de Minas Gerais SA

, whose shares fell by 1.28 percent.
