German Finance Minister Wolfgang Schaeuble and French counterpart Pierre Moscovici wrote to European Taxation Commissioner Algirdas Semeta and their 25 EU colleagues seeking permission for an "enhanced cooperation" accord which could be implemented if one third of all EU states back it.

The two ministers say in their letters, undated according to copies seen by AFP on Friday, that their governments "request" that the Commission formally ask the 27 EU member states for "a decision authorising enhanced cooperation with regard to the creation of a common system of financial transaction tax."

A bid to introduce the tax aimed at curbing the market excesses that led to the 2008 global financial crisis in all 27 EU states failed in June, in part due to British concerns over the City of London's future.

Under its provisions, the Commission would have levied a 0.1 percent tax on share and bond trades, and 0.01 percent on other transactions, generating billions of euros in revenue.

France and Germany hope the FTT can be operational by the end of this year based on the support of nine states but they will need at least tacit permission from London and other opponents who would not be joining in.

The European Commission said it welcomed the French and German initiative "as a means of keeping up the momentum behind an EU FTT.

"We believe that that the FTT has huge benefits to offer, even if applied by a limited group of member states," said Emer Traynor, spokeswoman for Semeta.

"We therefore urge the other interested states to send their letters of request to reach this quota. Citizens are waiting for this tax, so the sooner it can progress, the better," Traynor added.
