Protesters threw petrol bombs during a protest in Caracas on Saturday.

If it were not afraid, it would not close the streets ... It would not disqualify Capriles," said 27-year-old lawyer Gikeissy Diaz, adding that half of her graduating class has left the country and that she is thinking of doing so, too. Capriles, a two-time presidential candidate and Miranda state governor, who was seen by many as the opposition's best chance in the presidential election scheduled for 2018, on Friday was banned from holding political office for 15 years. The order from the national comptroller's office cited "administrative irregularities" including breaking contracting laws and improper management of donations, according to a copy of the ban.

Around the same time, around a hundred protesters broke into an office of the Supreme Court and vandalised it, throwing construction materials inside and lighting a fire, according to a Reuters witness.

Mr Capriles had urged a crowd of supporters in Caracas to march to the office of the state human rights ombudsman, whom the opposition says is a puppet of the government.

After a recall referendum against Mr Maduro was quashed last year and amid fears that next year's presidential election will not be fair, opposition supporters say they have no option but to take to the street. But after years of marching many are cynical, while others are too busy trying to find food. Venezuela has been pummelled by a brutal economic crisis that has millions skipping meals, unable to afford soaring prices for basic goods and facing long lines for scarce products. Venezuela's opposition says the security forces have been unnecessarily violent during the protests. Credit:AP Others have been motivated by the escalating political crisis and the opposition coalition is putting on a more dynamic and co-ordinated front than usual. "It's been two years since I've been out on the streets," said Richard Morton, a 43-year-old electrical engineer who said shortages make it tough to import medical equipment needed in his work, as he prepared to march under Caracas' hot sun.

"I'm out today because I see people acting in solidarity and the lawmakers are backing us up more. Plus the economic situation is insufferable. No one can live here." Oil-rich Venezuela is in the throes of what is thought to be a fourth straight year of recession, with roaring inflation and monthly wages stuck at a handful of dollars at the black market rate. The opposition will protest again on Monday and then on April 19 will hold what leaders described as "the mother of all marches" during a Saturday night press conference. Venezuela's powerful new Vice-President, Tareck El Aissami, declared Saturday's march in Caracas "illegal and unconstitutional", because the opposition had not received official permission for it. Over the past few days, authorities accused the opposition – and Mr Capriles in particular – of fomenting violence and bloodshed by leading increasingly intense protests against Mr Maduro.

"They're seeking a provocation, that will lead to violence," El Aissami said on Friday, adding the march could block crucial services such as ambulances. The opposition said it is security forces who are unnecessarily violent. A 19-year-old man was shot dead in violence around protests on Thursday, and a police officer has been arrested. Rights group Penal Forum said almost 100 people have been arrested during protests in the last few days. The opposition said more than 100 political activists have been jailed amid a wider crackdown on dissent. Amid growing global condemnation of Mr Maduro, several Latin American nations criticised the move against Mr Capriles. Loading Argentina's foreign ministry said in a statement the decision would have a "negative impact" on the right of Venezuelans to choose their leaders.
