UPDATE 1-Mexico's Sheinbaum not planning fiscal reform in first years if elected, advisor says

(Adds details on Sheinbaum's plan for the economy)

MEXICO CITY, April 3 (Reuters) - Mexican presidential candidate Claudia Sheinbaum would not carry out a fiscal reform in the first years of her administration if elected in the upcoming June vote, her advisor was quoted as saying in a podcast published by Grupo Financiero Banorte on Wednesday.

Sheinbaum's economic advisor Altagracia Gomez said her efforts will focus on pulling about 55% of Mexico's economy away from informality before doing any fiscal reform.

Sheinbaum, the former Mexico City mayor representing the ruling leftist National Regeneration Movement (MORENA), is

leading the polls

.

There will be a lot of fiscal responsibility and debt will not rise, Gomez said.

The candidate's advisor added the country's transition to renewable energy would be a "trademark" of her government, something the candidate has

pledged for

in the past. (Reporting by Ana Isabel Martinez; editing by Cassandra Garrison)
