The SNP "candidate" for Edinburgh North & Leith is always on the look out for new ways to talk down the single biggest public investment in his potential consitituency, the Trams, as if he's determined that Leith will get as little benefit from it as possible. And, I'm annoyed with myself for even rising to his crass political opportunism, but I have. Again.

This time he's pretending to be able show us how the tram project will destroy Lothian Buses.

The main plank in his argument seems to be that the rising costs of the tram project, combined with the economic downturn will see the City of Edinburgh Council saddled with lots of debt. To pay it, they'll need to sell Lothian Buses.

That is indeed one possible scenario, if the Scottish Government doesn't change it's tune and start investing in public transport. I've said it before, and I'll say it again. If the SNP will choose to prioritise transport investment in shaving seconds from car journeys between SNP target seats, or building immensely expensive congestion generating bridges, then, even if you believe Calum with his conjecture based assessment of Lothian Buses business, it will be the fault of the SNP if the City of Edinburgh council have to sell Lothian Buses. No-one elses.

The SNP controlled Scottish Government should cover any funding gap that results from tram project overruns - just as they do for road building projects, like the M74 extension.

Please, Calum, change the record. No-ones going to vote for you if you carry on with this 'voice of doom' chat.
