European shares rose on Monday, led by Aggreko after a bullish trading update, although concern the U.S. Federal Reserve will start scaling back its stimulus at this week's policy meeting could crimp market gains, Reuters reported. The FTSEurofirst 300 was up 0.3 percent at 1,246.11 points by 0902 GMT, while the euro zone's blue chip STOXX 50 rose 0.5 percent to 2,937.71 points. Recent robust U.S. data along with last week's breakthrough budget deal in Washington fuelled speculation that the Fed will announce a reduction to its $85 billion of monthly bond purchases on Wednesday.
