Benigno “Noynoy” Aquino III, the son of a former president and an assassinated opposition leader, has been sworn in as the 15th president of the Philippines.
Thousands of people attended the eagerly-awaited ceremony in Manila and he used his first speech to promise to tackle corruption and improve the lives of the poor.
Aquino also said he would seek a solution to a long-running Muslim separatist insurgency in the south.
Many in the crowd wore yellow, the colour of the 1986 popular revolution that swept Aquino’s mother Corazon to power.
The wave of emotion following her death last August, along with the family’s reputation for propriety and honesty, helped Aquino surge to the presidency.
The previous two administrations, led by Gloria Macpagal Arroyo, were dogged by allegations of corruption, electoral graft and rights abuses. She denies any wrongdoing but the claims will now be investigated by a “Truth Commission” set up by Aquino.
