Opposition keeps up pressure on Arroyo

Opposition groups held small demonstrations in the capital to call for Arroyo to quit, after thousands gathered in similar rallies late Friday, while various opposition factions met to plot their next move.

One opposition leaders admitted, however, that their efforts were weakened by having no clear replacement for Arroyo if she is forced to step down.

"The difficulty ... in rallying enough support is that we are now in a crisis of leadership -- a crisis of who will replace President Arroyo," Senator Jamby Madrigal said in an interview with ABS-CBN television.
