I cannot offer proof, as that is for a court, but the 'evidence' that is in the public domain points to M16 knowing he was about to board a plan for London (they had approved it) and then telling the US who arrested him and handed him to Gadaffi.
// It emerged on Monday that MI6 had been able to tell the CIA of his whereabouts after his associates informed British diplomats in Malaysia that he wished to claim asylum in the UK. Belhaj was then allowed to board a flight for London and abducted when the plane called at Bangkok.
There were signs that the discovery of a cache of secret MI6 and CIA documents at an abandoned government office building in Tripoli was triggering panic in some parts of Whitehall.
The papers detail the UK's role not only in the rendition of Belhaj, but in that of a second man, known as Abu Munthir. This operation appears to have been planned by British and Libyan intelligence officers without any CIA involvement. //
