sentences:  Speaker De Venecia "challenged" everyone to support his new proposal for the election of constitutional convention delegates to be held on the same day as the May 2007 local elections.Despite the concessions made by Speaker De Venecia, opponents ignored his new proposal and still pushed through with the rally that was supposed to reach 500,000 to 3,000,000 people.However, the turnout based on Director Wilfredo Garcia's (chief of Philippine National Police-Directorate for Operations) and other media reporter's estimate did not grow beyond 15,000 and was significantly composed of members of left-wing organizations.
