UK stocks fell on Monday morning, pulling back following the strong end to last week, with Greece once again in focus as government talks enter a critical stage.After a meeting last night between the three parties of Greece's coalition government, Prime Minister Lucas Papademos announced that they had agreed on "basic issues". However, Greek paper ekathimerini has reported that the two smaller party heads remain opposed to excessive austerity and that talks will continue today. Negotiations continue to crawl forward and Greek finance minister Evangelos Venizelos described the difficulties: "The gap between the successful completion of procedures and a deadlock, which could be accidental or due to a misunderstanding, is very small. We are on the razor's edge," he said. Greek leaders meet again this morning with an 11:00 deadline in Athens to reach a final deal. According to Barclays Capital analysts, "the economic outlook in the euro area is still fragile and the risk of a disorderly outcome from Greece has increased following Greek party leaders opposition to the Trokia demands for new austerity measures at the same time as a lack of agreement over the Greek PSI remains."RANDGOLD RISE AFTER Q4 RESULTSRandgold Resources, the west Africa-focused gold miner, saw sales in the final three months of last year rise 1.3% over the the previous quarter.
