DEAUVILLE, France (AFP) - The G8 world powers threw the rich worlds weight behind the Arab Spring on Friday, demanding Libyan strongman Moamer Gaddafi step down and pledging billions for fledgling democracies. G8 summit host President Sarkozy of France outlined Friday a $40 billion package of aid and loans for the countries of the Arab Spring, Tunisias finance minister said. Whereas the statement agreed by G8 leaders did not put a figure on support for the Arab world, Tunisias new finance minister said the total package of aid and loans would amount to $40 billion (28 billion euros). Democracy lays the best path to peace, stability, prosperity, shared growth and development, the leaders declared, after meeting with prime ministers from post-revolutionary Tunisia and Egypt seeking support for reform. Presidents and prime ministers of Britain, Canada, France, Germany, Italy, Japan, Russia and the United States met in the French resort of Deauville on the second and final day of the annual Group of Eight summit. Under the chairmanship of host President Nicolas Sarkozy of France, they took a tough line with the regimes resisting pro-democratic revolts, warning Libya and Syria to halt the violent repression of their own peoples. We demand the immediate cessation of the use of force against civilians by the Libyan regime forces as well as the cessation of all incitement to hostility and violence against the civilian population, they said. Gaddafi and the Libyan government have failed to fulfil their responsibility to protect the Libyan population and have lost all legitimacy. He has no future in a free, democratic Libya. He must go, it warned. US President Barack Obama said after talks with Sarkozy that we have made progress on our Libya campaign referring to NATOs air strikes in support of rebel forces and vowed: We are joined in resolve to finish the job. With popular revolts sweeping the region, the G8 was expected to pledge billions in aid to help Tunisia and Egypt along the path towards democracy.
