Mohammed al-Senousi describes himself as a prince, although he has had no throne since his grandfather was ousted in a 1969 coup by Moammar Gadhafi.
Al-Senousi, 42, joined hundreds of Libyan opposition members in London on Saturday to push for Gadhafi's ouster — their first conference in exile to tell the world, they said, there is an alternative to Gadhafi that is not "Islamic extremism".
The organizers condemned the West, particularly the United States, for normalizing ties with Libya, charging Washington was practicing double standards when it came to human rights violations in the North African nation.
"It forgot Libya and its bloody dictator regime" while urging reform in other Arab countries, a statement said.
