More than 6,000 police officers were deployed around the Philippines' Senate on Monday as the impeachment trial of Vice President Sara Duterte got underway, with protests by both supporters and detractors taking place near the building.

The trial, which will reportedly last for 92 days, comes against the background of a growing feud between the two most influential political dynasties in the Philippines, the Dutertes and the Marcoses.

It marks the first time a vice president of the Philippines has faced a Senate impeachment court.

What charges is Sara Duterte facing?

Last month, the House of Representatives, dominated by allies of President Ferdinand Marcos Jr., voted overwhelmingly to impeach the vice president.
