The FTSE 100 is edging towards 5,800 early on amid a wave of optimism Greece will pass its five-year austerity plan.
Greece's parliament is set to vote today on the package of austerity measures the country needs to secure in order to receive another tranche of bailout money from the European Union and the International Monetary Fund.
Ahead of the vote, traders have been buoyed by yesterday's announcement by France that it had struck a deal with its banks who hold maturing Greek debt.
French banks agreed to rollover their Greek sovereign debt in a move which could provide a blueprint for other countries, and a resolution to the Greek crisis.
