CARACAS, Venezuela - President Hugo Chavez told US officials to "Go to hell, gringos!" on his weekly radio and TV show Sunday for what he called unacceptable meddling after Washington raised concerns about a measure to grant Venezuela's leader broad lawmaking powers.

The National Assembly is expected to give final approval this week to what it calls the "enabling law," which would give Chavez the authority to pass a series of laws by decree during an 18-month period.

On Friday, US State Department deputy spokesman Tom Casey said Chavez's plans under the law "have caused us some concern."

Chavez rejected Casey's statement in his broadcast, saying: "Go to hell, gringos! Go home!"

Among Chavez's plans are nationalizing the main telecommunications company and the electricity and natural gas sectors.

The president's opponents accuse him of using his political strength to expand his powers.

Relations between Caracas and Washington have been tense since Chavez was briefly ousted in a 2002 coup that he claimed the US played a role in. The Bush administration has repeatedly denied being involved.

Chavez has consistently accused the US of conspiring to oust him and often asserts the CIA is working to destabilize his government. US officials have denied trying to overthrow Chavez, but they have labeled him a threat to democracy.

Criticizing excessive consumption and self-indulgence, Chavez also announced plans in his broadcast to raise domestic gasoline prices and approve a new tax on luxury goods such as private yachts, second homes and extravagant automobiles.

He did not give details on the gas price hike, which he said would not affect bus drivers who provide public transportation, or the luxury tax. He said revenue from the new measures would be put toward government social programs.

Venezuela is one of the world's leading petroleum exporters and gasoline now costs as little as 12 cents a gallon due to government subsidies.

In typical style, Chavez spoke for hours Sunday during his first appearance on the weekly program in five months. He sent his best wishes to the ailing Cuban leader Fidel Castro, his close ally and friend who has been sidelined since intestinal surgery last summer.

Chavez also remarked on the hanging of former Iraqi President Saddam Hussein: "They took out Saddam Hussein and they hanged him, for good or worse. It's not up to me to judge any government, but that gentleman was the president of that country."
