Libyan Foreign Minister Moussa Koussa arrived in the U.K. on Wednesday and is resigning from his post, Britain's government said.
Moussa arrived from Tunisia at Farnborough Airport, about 35 miles (55 kilometers) southwest of London, the Foreign Office said in a statement, adding that he traveled here under his own free will.
"He has told us that he is resigning his post," the statement said. "We are discussing this with him and we will release further detail in due course."
It was not immediately possible to confirm the statement with Moussa or people close to him.
"We encourage those around (Libyan leader Moammar) Gadhafi to abandon him and embrace a better future for Libya that allows political transition and real reform that meets the aspirations of the Libyan people."
