this whole release was bullshit. God i hate the UK with a passion
The release of the Lockerbie bomber was tied to trade deals between Libya and the UK, reports quote the son of Libyan leader Colonel Gaddafi saying.
Seif al-Islam told Libyan TV the case was raised during talks over oil and gas, AFP news reported. The UK Foreign Office has strongly denied the claims.
Scotland's government freed terminally ill Abdelbaset Ali al-Megrahi, 57, on compassionate grounds on Thursday.
Megrahi told the Times he would present new evidence proving his innocence.
The man convicted of killing 270 people aboard a transatlantic airliner in 1988 said he would present the evidence through lawyers in Scotland and ask the British and Scottish communities to "be the jury".
Colonel Gaddafi's son had labelled Megrahi's release a "victory".
In an interview with a Libyan station, he reportedly claimed that the Megrahi issue had been raised repeatedly by Britain's former prime minister Tony Blair.
"In all commercial contracts, for oil and gas with Britain, (Megrahi) was always on the negotiating table," Mr Islam said told Libya's Al Mutawassit channel.
Mr Blair visited Libya in May 2007, during which UK energy giant BP signed a $900m (£540m) exploration deal.
However, the Foreign Office insisted Megrahi's release had been a matter solely for the Scottish authorities.
A spokesman said: "No deal has been made between the UK government and the Libyan government in relation to Megrahi and any commercial interests in the country."
UK Foreign Secretary David Miliband earlier rejected suggestions the UK pushed for Megrahi's release to improve relations as "a slur on both myself and the government".

Separately, the Foreign Office was unable to confirm whether a planned trip to Libya by the Duke of York in September would be cancelled.
A spokeswoman said an official invitation to the British government from Libya had not yet been received.
However, it is believed any visit is unlikely to go ahead in light of the furore surrounding Megrahi's return.
The bomber's release - and the hero's welcome he was given on return to Libya - provoked anger from many relatives of those who died aboard Pan-Am flight 103, particularly in the US.
President Barack Obama condemned the jubilant scenes at Tripoli airport as "highly objectionable".
The UK foreign secretary described TV footage of people greeting Megrahi by cheering and waving flags as "deeply distressing".
Scottish First Minister Alex Salmond also said the reception was "inappropriate".
UK Prime Minister Gordon Brown has so far made no comment, although it has emerged he wrote to Colonel Gaddafi to ask that Libya "act with sensitivity" in its welcome.
