London, Jul 2 (Prensa Latina) Dozens of supporters of Julian Assange and his partner, Stella Moris, embarked on a Thursday boat trip on the Thames River in central London as part of a growing campaign of protests to demand the release from prison of the WikiLeaks founder. Video footage posted on social media showed the boat sailing from Festival Pier and briefly stopping outside the Houses of Parliament before continuing down the river to the US embassy in Vauxhall.
