Bear Grylls | Dan Kitwood/Getty Images for Land Rover Bear Grylls swaps drinking urine for Tory conference Survival expert asks for more money for the Scouting movement.

A survival expert who appeared on television drinking his own urine and eating goat testicles gave a speech at the Conservative Party conference in Manchester on Tuesday.

Bear Grylls took to the stage in his capacity as Chief Scout — the public face of the Scouting movement — and called for more investment to help young people.

"I am not here as Bear Grylls. I am here to champion young people desperate for a voice," he said. "If I was prime minister, and I could make a relatively small investment in scouting, that £50 million would be the best money I'd ever spent. Truth."

He added that the Scouting movement was incredibly popular.

"If you ignore young people, you perish ... We have young Muslim men and women joining our ranks in the thousands. In fact, we’re experiencing such overwhelming demand that even as a leading U.K. youth charity, as Scouts we cannot keep up — not by a long margin."

Grylls' late father, Michael Grylls, was a Conservative politician.

Former U.S. President Barack Obama once guest-starred on an episode of the TV show "Running Wild with Bear Grylls." However, Obama refused to drink his own urine.
