Cameron is in a constant spin of Cobra meetings and high powered talks. The language he has used against Colonel Gaddafi has been more aggressive than any other world leader.

Speaking to Sky's Lisa Holland, Colonel Gaddafi's most high-profile son derided Mr Cameron and claimed Britain needed "to stop thinking greedily about oil".

He referred to the Prime Minster's response to the Libyan crisis as "a joke" and said "we are not listening to him".

Refusing to accept that the Libyan government has lost control of the east of the country, Saif Gaddafi called the rebels occupying the city of Zawiyah "terrorists" and reiterated his stance that he would live and die in Libya.
