The final cost of Edinburgh's tram project could reach £750m - £250m more than originally planned, according to a senior MSP.
SNP MSP Shirley Anne Somerville also said sources close to the project said trams may not start running until 2013, two years later than expected.

The project's cost was originally estimated at £498m.read more
