Libyan embassy to reopen under NTC
The Libyan embassy is due to officially reopen under the control of the National Transitional Council (NTC).
Opponents of Muammar Gaddafi's regime are to hoist the new independence flag above the premises in London.
Foreign Secretary William Hague announced last month that Britain was recognising the NTC's authority and expelling the last of the dictator's representatives.
Mahmud Nacua, the newly appointed charge d'affaires, will lead the reopening ceremony on Tuesday afternoon.
Participants will include Libyans who have had family members killed in the conflict.
Mr Nacua said: "The reopening of the embassy symbolises how far we have come.
"The embassy represents the legitimate government of Libya and in line with this will serve all the Libyan community irrespective of their political allegiances.
"We will also continue to struggle for greater freedom for the Libyan people and Gaddafi's departure from Libya.
"I thank the British Government for its decision to recognise the NTC and its steadfast support for the Libyan people throughout our fight."
