Sunday’s demonstration in Manila to coincide with anniversary of 1972 martial law declaration as president backs rally in bid to placate anger

Thousands of people are expected to join a mass protest in Manila on Sunday amid a groundswell of anger in the Philippines against perceived corruption in government-funded flood control projects.

Dubbed the “Trillion Peso March”, the demonstration is named after a Greenpeace estimate of $17.6bn that the environmental organisation alleges is the amount skimmed from climate-related projects in 2023.
