UK stocks fell in early trading on Tuesday, giving up some gains made yesterday, as talks in Greece continue to drag on.Despite banks and other private institutions represented by the Institute of International Finance (IIF) having presented yesterday what they considered to be their "maximum offer that is consistent with the voluntary debt exchange", Eurozone finance ministers could not be coerced to sign off on the proposal for Greek debt and responded with a resounding "no".According to Barclays Capital analyst Cagdas Aksu, "it seems the negotiations are stuck mainly around the coupon of the new bonds, with the Greek government offering 3.5% while the private investors want at least a 4% coupon."The Eurogroup members that met yesterday in Brussels decided to back Athens. Its president, Jean-Claude Juncker, agreed that the Greek coupons need to be below 3.5% for the debt to be paid up to 2020 and that it should be below 4% for the full 30 year life of the bonds.CAIRN & FINANCIALS DRAG FTSE 100 LOWERCairn Energy has withdrawn its proposal to give its non-executive Chairman, Sir Bill Gammell, share options worth £2.5m.
