Hundreds of British citizens remain in Libya, the Foreign Office has said.
The Government estimated 220 UK nationals were in the country, with 100 telling officials they wanted to stay.
Another 70 said they might choose to leave "at some point".

Mr Burt revealed the situation in a written Parliamentary answer to Romford Tory MP Andrew Rosindell.
