UK accused over Musa Kusa exit
Ministers have been accused of allowing Britain to become a "transit lounge for alleged war criminals" following the disclosure that Libyan defector Musa Kusa had been allowed to leave the country.
The Foreign Office confirmed that Colonel Muammar Gaddafi's former right-hand man was travelling to the Gulf state of Qatar ahead of international talks there on Libya.
A spokeswoman said that Kusa - an ex-intelligence chief who has been linked to the 1988 Lockerbie bombing - was "free to come and go" from the UK as he wished.
She said that he would be offering his "insights" on the current situation in Libya to representatives of the Qatari government and others attending the contact group talks in Doha.
However Conservative MP Robert Halfon, whose family fled Libya when Gaddafi took power, said the Government was repeating the mistakes made over the release of the Lockerbie bomber Abdelbaset al-Megrahi.
"Many people will be very anxious that Britain is being used as a transit lounge for alleged war criminals," Mr Halfon said.
"We should learn from the release of Megrahi that we should not release those people associated with Gaddafi or let them out of the UK until they have faced the full course of the law, whether in British courts or international courts."
Brian Flynn, whose brother died in Lockerbie and who now organises the Victims of Pan Am 103 Incorporated group in the United States, said the British Government was being "played" by Kusa.
"He is not the suave diplomat in the suit sitting on the sidelines, he is one of the key guys who masterminded (the bombing of) Pan Am flight 103," he told The Guardian.
"He is a stated enemy of the British government. The Scottish and American prosecutors on Lockerbie are being betrayed by the politicians and the diplomats. Cameron has been good on Libya, but this sounds an awful lot like Tony Blair is back in charge."
