LONDON, Jan 14 - The euro was weaker against the dollar on Wednesday as markets used this week's expressions of concern by European policymakers over the single currency's recent record highs as an opportunity to lock in profits. European central bankers, ministers and heads of government have expressed concerns about the economic impact of the euro's 40 percent rise versus the dollar over the past two years and especially the accelerated pace of its recent gains. But U.S. officials have offered no solace, including Federal Reserve Chairman Alan Greenspan who indicated on Tuesday the weaker dollar had not caused inflation worries. At 0751 GMT, the euro was down 0.30 percent at $1.2724 as markets remained in consolidation mode after pushing it to record highs of $1.2898 on Monday. The euro was down a third of a percent against the yen at 135.10 . The dollar was stable against the Japanese currency at 106.16 yen but near three-year lows around 105.88. Data scheduled for release at 1330 GMT is expected to show a widening U.S. trade deficit, which could heighten worries about dollar weakness. U.S. producer prices are also due at 1330 GMT, the Federal Reserve's Beige Book of regional economic conditions at 1900 GMT and a host of Fed speakers throughout the U.S. afternoon session.//
