MANILA, JULY 9 -- President Corazon Aquino today applauded the U.S. warning to deposed ruler Ferdinand Marcos, which allegedly derailed a plot by Marcos to overthrow the Philippine government.

Presidential spokesman Teodoro Benigno warned that Marcos might still attempt to seize power before the new congress convenes July 27.

But Marcos' attorney Rafael Recto ridiculed the allegations as "impossible" and "silly."

State Department officials in Washington confirmed warning Marcos that he would not be allowed to leave his home in Honolulu -- where he has lived in exile since 1986 -- without permission from Manila.

"I am very pleased that this {U.S.} statement came about at this time that, again, rumors are circulating that Mr. Marcos and or Mrs. Marcos are planning to return home," Aquino said. "This should put these rumors to rest."

Philippine officials today released additional details of Marcos' alleged plot to outfit a 10,000-member army to overthrow Aquino.

Ramon Diaz, chairman of the government commission trying to recover wealth Marcos allegedly stole from the Philippines during his rule, released portions of a transcript of one of three taped conversations in which Marcos allegedly tried to procure arms.

In the transcript, Marcos asks a man posing as an arms dealer for armored personnel carriers, recoilless rifles, 50-caliber machine guns, 105mm howitzers, 8,000 M16 automatic rifles and a three months' supply of ammunition worth as much as $25 million.

Diaz said the conversation was recorded May 27 in Honolulu. The tape was turned over to a Philippine government lawyer in Paris, he said.

Luis Villareal, head of Philippine intelligence, said Marcos had planned to take Aquino hostage.

"With the warning of Reagan, the plan of Marcos is aborted," he said.
