European stocks were little changed near a five-year high after Federal Reserve Chairman Ben S. Bernanke signalled the central bank will maintain stimulus measures to support the U.S. economic recovery.

The Stoxx Europe 600 Index added 0.2 percent to 310.59 at the close of trading. The gauge, which yesterday climbed to its highest level since June 2008, has rallied 97 percent since March 2009 as European Central Bank President Mario Draghi pledged to preserve the euro and the Federal Reserve embarked on three rounds of stimulus.

The U.S. economy remains hampered by high unemployment and government spending cuts, and tightening policy too soon would endanger the recovery, Bernanke said today in testimony prepared for a hearing at the Joint Economic Committee of Congress in Washington. The Fed chairman is leading the most aggressive economic stimulus in the central bank's 100-year history in an effort to spur growth in the world's largest economy and reduce an unemployment rate that stands at 7.5 percent.

In the U.K., Bank of England Governor Mervyn King was defeated for a fourth month in his bid to expand stimulus. Six members of the Monetary Policy Committee voted to keep quantitative easing at 375 billion pounds ($568 billion) this month, according to minutes from the BOE's May 8-9 meeting. King, David Miles and Paul Fisher backed increasing it by 25 billion pounds.
