London midday: Stocks rise but markets cautious ahead of Eurogroup

- Greece approves 2013 budget - Japanese GDP worse than expected - Markets await Eurogroup meeting this afternoonUK stocks were continuing to trade slightly higher on Monday morning after Greece approved its 2013 budget late last night, however, gains were only modest as caution sets in ahead of the Eurogroup meeting.Greece's parliament put the rubber stamp on its budget for 2013 late Sunday night with a wide margin as 167 deputies approved the bill, 128 voted against, four voted 'present' and one member was absent. Passage of the budget was a requirement for Athens to get the green light on the next tranche of aid. However, the Troika is not expected to be able to give the final seal of approval necessary in time for today's meeting of Eurozone finance minsters. "Greece has done its part in agreeing the measures with the Troika and has taken the first step towards implementing them, it's now down to Greece's creditors to hold up their side of the bargain," said analyst Craig Erlam from Alpari."The decision on this is likely to be taken at the end of the month, meaning three weeks of uncertainty lie ahead. It's very unlikely to not be signed off though, a Greek default is in no one's interest."The Eurogroup, which is composed of the finance ministers from Eurozone countries, will meet this afternoon at 16:00 London time, when they are expected to discuss current developments in Greece and Spain.
