It's the final and the three remaining teenagers get to go on the trip of a lifetime as they travel with Unicef to research children's rights in Malawi, southern Africa.
The Speakers meet their African peers and study the right to survival, education and water. It's an emotional journey. On their return, they step on to the stage for the final time and speak about their experiences in front of a packed audience.
Judges Jo Brand, John Amaechi and Jeremy Stockwell, are joined by mentors Alastair Campbell, Deborah Meaden, Lord Spencer and Kate Silverton. For the three Speakers it's the culmination of months of work, but only one can win the title of The Speaker.
