Barclays has been fined €600,000 by  the Spanish financial regulator for under-estimating the risk of bonds sold to clients.

CNMV,t he country's stock market watchdog, hit the bank with the penalty, serving it to Barclays Bank's Spanish division over four structured bonds sold to clients between January and March 2008, the Times reported.

The latest fine draws a close on what has been a difficult year for Barclays globally, with the Libor manipulation scandal during the summer forcing its former chief executive Bob Diamond (pictured) to quit along with two other senior executives.

The investigation over Libor also resulted in a record £290 million fine, and the bank had to install a new chief executive to help repair its reputation.
