Philippa Langley from ‘The Lost King’ hosts new Princes in the Tower documentary

Channel 4 has announced a “revelatory” new documentary about the Princes in the Tower.

Hosted by Philippa Langley, the continent-crossing 90-minute doc is set to “open up one of English history’s greatest mysteries.”

If you’ve seen last year’s brilliant The Lost King movie, you’ll recognise Philippa’s name.

Played by Sally Hawkins in the dramatisation, Langley is the real-life writer who located the final resting place of King Richard III in 2012.

Channel 4’s The Lost Princes documentary sees her team up with criminal barrister Rob Rinder to deliver “an immersive investigation that will call into question everything we think we know about this notorious incident in our royal past.”

“Did Richard III orchestrate the brutal murder of the two young princes, his nephews Edward and Richard, as Shakespeare claimed?” the official synopsis teases. “Or does this famous cold case contain a more complex truth?

“A decade on from making worldwide headlines with the spectacular discovery, exhumation and reburial of Richard III, Philippa is back – this time armed with a stack of fresh leads provided by her team of researchers from across the globe.

The Lost Princes follow Philippa and Rob on a road trip that will take them across seas, into archives and deep into the heart of medieval Europe. Can they find England’s missing royals?”

“It’s been an extraordinary journey filming The Missing Princes Project and its (now) seven-year cold case investigation into the mystery of the Princes in the Tower,” commented Philippa Langley.

“By throwing out old mythology and starting with a clean sheet we were able to bring evidence-based research to life on our screens, revealing the most remarkable discoveries, and writing a new chapter in the study of this centuries-old puzzle.

“For all those interested in history, and this enduring mystery, this feature-length documentary is going to be unmissable viewing.”

Her co-host Rob Rinder added: “To be part of unlocking and investigating one of history’s most fascinating unsolved mysteries is quite special and I look forward to people coming on this journey with us.”

The Lost Princes will premiere in the UK this autumn on Channel 4.

“After years of determined research, Philippa Langley and The Missing Princes Project have unveiled a series of revelations that could revolutionize our perspective on a notorious period in royal history – the enigma of the Princes in the Tower,” said executive producer Malcolm Brinkworth.

“Through Rob Rinder and Philippa’s eyes, audiences will be taken inside this immersive and exciting new phase in the search for the lost princes,” he added.

The Lost King is available to watch on Acorn TV with this free 7-day trial.
