MANILA (Reuters) – President Rodrigo Duterte seemed unfazed when a finger-sized cockroach scrambled onto his shoulder as he spoke at a campaign rally in Garcia Hernandez town on Wednesday night.

Duterte, 74, was endorsing Senate and local bets including gubernatorial candidate Leoncio Evasco, Jr.  at the event when the insect ran up his left shoulder.

A female aide hurried forward to flick the bug off, but it ran down the front of the president’s shirt. Alerted by his anxious aide, Duterte swatted the roach away.

He then stomped on the floor and joked that the insect may have been planted by the main opposition Liberal party.

“It’s Liberal! That’s for sure,” Duterte said to laughter from the crowd.

Duterte then continued with the rest of his two-hour speech.
