Spain to attend G20 summit - French source

BRUSSELS, Nov 7 (Reuters) - Spain will attend next week’s G20 summit in the United States on the financial crisis, a French source said on Friday, but Spanish Prime Minister Jose Luis Rodriguez Zapatero said he had yet to receive an invite.

Germany, France, Britain and Italy, Europe’s four largest economies, have long been planning to attend, but Europe’s fifth-largest economy Spain had been left off the list.

“It has been decided that these seats will be occupied by Germany, Italy, France, Britain and Spain, the eighth economy of the world, to which there will also be added the president of the European Commission, Jose Manuel Barroso,” said an aide for French President Nicolas Sarkozy who declined to be named.

Zapatero said Spain should attend because of its economic standing and the relative strength of its banks, but it was ultimately for U.S. President George W. Bush to decide.

“Spain should attend this summit on the financial system because of its economic and political weight, and in my opinion we have gained ground with this argument,” he told reporters.

Sarkozy, who first proposed the summit last month, had previously said he wanted to include India and China, together with the world's richest nations. But Spain was not on the list despite being home to the biggest bank in the euro zone, Santander SAN.MC.

Spanish officials had already been fuming over Sarkozy’s failure to invite Spain to an impromptu European summit on the financial crisis in Paris earlier in October. (Reporting by Emmanuel Jarry and Julien Toyer, writing by Pete Harrison)
