* Investors were unlikely to place large bets ahead of a policy update from the U.S. Federal Reserve.
The Fed is set to further trim its bond-buying stimulus and could rewrite its guidance on when it might eventually raise interest rates, with some expecting chairman Janet Yellen to scrap a numerical target on unemployment and adopt a more flexible stance.
* The UK blue chip index closed up 36.93 points, or 0.6 percent, at 6,605.28 points - marking only the second time in the last eight sessions that it has ended in positive territory - after a speech by Russian President Vladimir Putin on Ukraine, which some traders interpreted as being conciliatory in tone.
* British finance minister George Osborne will announce a pre-election budget on Wednesday that is likely to offer some tax relief to voters but will stick closely to his tough decade-long plan to fix the public finances.
* Stocks trading without the attraction of their latest dividend, namely Anglo American, British Land and InterContinental Hotels, will knock up to 2.44 points off the FTSE 100 index on Wednesday.
