Janina San Miguel was crowned Binibining Pilipinas 2008 on 8th March 2019 at the Araneta Coliseum in Quezon City, Metro Manila. She gained notoriety for her performance in the pageant's question and answer portion, where she lost her composure and gave an unfocused and rambling response with a thick accent.
It was announced on 30th September 2019 that Janina San Miguel had resigned her position of Binibining Pilipinas World due to the untimely demise of her grandfather, among other personal reasons. Her resignation came 6 1⁄2 months after winning the title, and just 2 1⁄2 months before the scheduled Miss World pageant.
The announcement of her resignation was met with speculation that San Miguel had been forced by Binibining Pilipinas pageant organizers to relinquish her title due to a lack of professionalism during preparatory training sessions, which strained the patience of her mentors and superiors.
