BEIRUT- Lebanon's central bank governor Riad Salameh on Tuesday denied any wrongdoing after a Lebanese government official told Reuters that Swiss authorities had opened an investigation into money transfers by him, his brother and an assistant.

"Both the prime minister and the president are in the loop on the European move," the government official said.

A statement by Salameh dismissed any allegations about transfers by him, his brother or assistant as "fabrications and false news".

Speaking in response to questions from Reuters about local media reports of an inquiry, Lebanese Justice Minister Marie Claude Najm said she had received a request for cooperation by Swiss judicial authorities. "I have submitted the request to the public prosecutor to do what is necessary," she said.

Lebanon is grappling with a deep financial crisis that has hammered the currency, spread poverty and prompted a sovereign debt default. The crippled banking system has cut people's access to their dollar accounts since last year.

Salameh, a former Merrill Lynch banker, has led Lebanon's central bank, Banque du Liban, since 1993.
