I HAD an unusual appointment on Saturday at a tent outside the British embassy in Mexico City. Estíbalis Chávez, a 19-year-old Mexican schoolgirl, had been camped on a street corner outside the compound for ten days, foregoing food. Her ongoing hunger strike is designed to persuade the British government to give her a ticket to the April wedding of “Príncipe Guillermo” and Kate Middleton. The ambassador, Judith Miller, has sent her a letter gently telling her that it’s not going to happen. “But I still have hope,” says Ms Chávez, who is very faint after ten days without food but has vowed to stay outside the embassy until her health gives way—or the wedding planners give in.
