MEXICO CITY (AP) _ Mexican President Ernesto Zedillo announced that he would postpone a working visit to the United States scheduled for next week after opposition politicians tied their approval of the trip to unrelated issues.

Opposition legislators in the House conditioned their approval of the visit to the passage of issues that ``have no relation with the president's trip,'' a news release from the president's office said. The statement Thursday didn't elaborate. Mexico's Televisa reported that the opposition was tied to budget issues.

Zedillo planned to meet with President Clinton in Washington next Wednesday and Thursday. The working visit, which would be the leaders' 11th meeting, was to include discussions on trade, drug trafficking and immigration.

The Senate unanimously approved the president's trip on Nov. 25, the release noted.
