MANILA, March 17 (Xinhuanet) -- The Philippine presidential palacesaid Friday it is prepared for any constitutional challenges to President Gloria Macapagal Arroyo and fight a new impeachment with the same resolve it demonstrated to foil a conspiracy to grab power last month.

    "This is a presidency and a government that cannot be pushed around by impeachers or coup plotters," Press Secretary and concurrent Presidential Spokesman Ignacio R. Bunye said.

    He dismissed a second impeachment case against President Arroyo,which is planned by some opposition congressmen, saying it is already defeated even before it could be launched due to "the sheer hollowness of the allegations and claims".

    "We are prepared for any constitutional challenges to the presidency and we shall fight impeachment with the same zeal and resolve we had in preempting and confronting extra-constitutional attacks," Bunye said.

    The opposition in the House of Representatives said they would file the second impeachment case against Arroyo in July.

    House minority leader Francis Escudero said on Thursday the opposition will file a second impeachment in July over alleged cheating in election and violation of the constitution by declaring a state of national emergency by Arroyo.

    The impeachment case filed against President Arroyo at the House of Representatives last year failed to gather the required two-thirds vote to send the complaint to the Senate for trial.

    The House later voted to quash the complaint for lack of substance. Enditem
