The British Prime Minister said in a recent interview that safe passage for Syria's president may be provided if he agrees to leave the country.
"I am certainly not offering him an exit plan to Britain, but if he wants to leave, he could leave, that could be arranged," Cameron told Al Arabiya television during his visit in Abu Dhabi.
The UK Prime Minister also said that his country would not arm the rebels currently fighting Assad.
Cameron's words come during a period of frustration for Western nations who are largely observing the deadly stalemate from the sidelines.
The British ambassador to the UN, Mark Lyall Grant, said that the UN Security Council had not discussed the possibility of giving Assad immunity and allowing him passage.
"My point is to make clear the we feel very strongly about accountability and believe that Assad and his regime should be brought to justice for the crimes they have perpetrated," he said, according to CNN.

"But there is also urgent priority to stop the violence and get a political dialogue going. It is incredible to think that the opposition would accept Assad as part of that transition. But exactly how that is achieved, we will wait to see."
The BBC reported that human rights group Amnesty International said that Assad would likely only leave if he was offered immunity.
"David Cameron should be supporting efforts to ensure that he faces justice, ideally at the International Criminal Court at The Hague," Amnesty International said in a statement.
It has been estimated that about 35,000 people have been killed in Syria since the beginning of the uprising that began in March of last year.
