The Panama Papers jail: Architects create concept prison ship that can hold 3,300 tax-avoiders in Game of Thrones-style 'sky cells'
- Last year, 11 million financial documents dubbed the Panama Papers were leaked from a law firm
- The leaked papers show how the world's rich and powerful use offshore tax havens to hide their wealth
- Architects have drawn up plans for a giant boat that could hold 3,300 prisoners in its paper sails
- The cargo hold contains a sea water-treatment plant, workshops and a gym while the sails are prison cells
