Should we pull the plug on Edinburgh's trams? With no end in sight to the row that's halted tram works on Princes Street since the weekend, fears are growing that costs could escalate. The organisation overseeing the project, Transport Initiatives Edinburgh (TIE), says that the contractors' demands could add £50m-£80m to the project. And, now, Nationalist MSP Shirley-Anne Somerville wants the auditor general to assess whether the project should be allowed to continue. Should we pull out before any more taxpayer's money is wasted? Or is this project far too important to our capital city's transport system? Graham Stewart takes your calls, texts and emails.
