In 2006 the Scottish Parliament passed laws to reintroduce a tram network to Edinburgh. However, in May 2007, the SNP won the Scottish parliamentary election and formed a minority government. The SNP want to scrap the tram scheme because they don’t think it gives value for money.
They may well be right that the tram scheme isn’t perfect, and it doesn’t represent the best value for money. But consider: the present tram proposals are the result of years of discussions and planning, and the Scottish Parliament’s term of office is only 4 years. If, after every election, the old govement’s plans are scrapped, then any scheme that takes significantly longer than 4 years is unlikely to go ahead.
So the tram scheme should be kept, because it will bring better transport facilities to Scotland’s capital, even if it isn’t perfect.
