Cameron's initiative - a dangerous game?

It will be interesting to see what the outcome is of David Cameron's attempt to seize the initiative regarding the independence referendum. Calton has already stated that he does not think the referendum should be this year however, reading between the lines of what Cameron said to Andrew Marr this morning, it sounds like he would like the referendum to be sooner rather than later. This puts Cameron on an obvious collision course with Alex Salmond and Calton's concern is that the focus will shift to yet another stushie between Holyrood and Westminster rather than concentrating on the arguments for or against independence. The last thing Scotland needs is to be bounced into an early referendum by Westminster. Calton thinks that Cameron is playing a dangerous game by increasing the pressure on Alex Salmond. Hopefully the First Minister will hold his ground.
