Meghan Markle’s estranged dad allegedly hid a secret stockpile of youngster porn among household mementos in his Philippines house, according to his son, who claims to have stumbled across the sickening stash.

Thomas Markle Sr.’s alleged trove of filth – which included“hundreds if not thousands” of vile snaps – was found by his son, Thomas Markle Jr., over the summer season, The Sun reported on Thursday.

Markle Jr. advised authorities that the photos were chillingly hidden among household mementos in 4 bins at his dad’s house in Cebu in July.

The Duchess’ half-brother had been looking for a telephone when he claimed he uncovered a 15-minute video of youngster pornography on an LG cell phone.

Children no older than age 10 or 11 were allegedly captured on the video.

There were also three photos of bare and scantily-clad women of about the same age on the gadget, according to The Sun.

One of the alleged photos was a picture taken of the display screen of a Lenovo ThinkPad laptop computer in a room Markle Jr. said he acknowledged from his dad’s ex-home in Rosarito, Mexico.

Markle Jr., 60, said he was a “shaking wreck” as he realized what he had stumbled upon before reporting the alleged discovery to the FBI hotline and state police in Pennsylvania — where Markle Snr., 82, was residing at the time.

He also reported it to the National Center for Exploited and Missing Children.

Meghan Markle said Friday she’s “deeply disturbed” by the reports.
