BHP heads risers with weaker Australian currency giving cost benefitsLeading shares have moved sharply higher on hopes that a solution to Greece’s financial troubles can be found, while mining groups have been boosted by an Australian interest rate cut.BHP Billiton is 75.5p better at 1559.5p after the Reserve Bank of Australia reduced its cash rate by 25 basis points to a record low of 2.25%, to help lift its economy and keep a lid on the Australian dollar.
