A big drive is under way in Venezuela to collect signatures for a referendum to remove 38 opposition deputies.
Chavez supporters praise his 'concern for the poor'
Some of these were allies of President Hugo Chavez, but defected reducing the government's majority in parliament.
The petition comes a week before the opposition hold their own signature drive to try to get rid of the president himself.
They accuse him of behaving like a dictator who has done little to fight rampant crime and a stagnant economy.
Nearly 2,000 collection centres have been set up on street corners across the country.
Some of the names at the top of the petition sheets used to support the government in parliament.
Now President Chavez blames them for blocking his programme of reform.
But there is much more at stake here.
The four-day long signature drive is being seen as an important test of government support ahead of the opposition's rival petition next week.
The loose coalition of politicians, business leaders and trades unions that make up Venezuela's opposition are hoping to collect enough signatures to secure a referendum on President Chavez himself.
The president's supporters praise his efforts to improve health and education - they say he is the first leader in Venezuela to show any concern for the poor.
After a botched coup last year and a two-month long national strike earlier this year, the referendum process is meant to offer a democratic way-out of the stand-off.
Both the government and the opposition say they will play by the rules, but after nearly two years of lurching from crisis to crisis, few expect it to be that easy.
