London this week summoned Libyan representatives of Moammar Gadhafi to inform them the TNC was recognized as the sole governmental authority in Tripoli.
Members of the NATO intervention in Libya at a recent meeting in Istanbul recognized the legitimacy of the TNC. London said it was working with the TNC to assign diplomats in the country to take the place of Gadhafi's.
Mark Toner, a spokesman for the U.S. State Department, said TNC officials have asked to set up a presence in Washington.
