Thousands of people marched to the Philippine presidential palace in Manila on Tuesday to mark Labour Day.

Around 5,000 workers and activists from various groups held a rally near the Malacanang palace to protest what they say is the failure of Philippine President Rodrigo Duterte to fulfill a major campaign promise to end all contractualisation, the widespread practice of short-term employment.

The protesters also demanded that the government address labour issues including low wages, unemployment and trade union repression.

A leader of a local labour group said that unions will continue to mount demonstrations, knowing that the government will not give in "without a fight".

Workers and activists around the world traditionally mark May Day with rallies and marches.
