The Chairman of Edinburgh Trams and Lothian Buses has quit with immediate effect, describing the city's tram project as "hell on wheels".
David McLetchie, Scottish Conservative MSP for Edinburgh Pentlands, said:

"David Mackay's parting comments underline that the relations have completely broken down between Tie and Bilfinger Berger.
"I believe we are heading for a divorce and that Bilfinger Berger will be sacked and that in due course blame, expenses and damages will be apportioned between the warring parties by the courts. In the meantime the Council need to put a new Chairman in place to succeed Mr. Mackay and step in to the contract so it can be progressed.
"Many local firms and workers are involved in the trams project who are perfectly capable of finishing the job and we should give them our support. The City Council must also show some leadership and take responsibility for a project which it commissioned."
Ruth: "Our thoughts should now be with the families of the victims who died on that fateful day in December 1988."
