This could fall into the SNP's hands and could be seen as London dictating to Scotland if the rules are decided at Westminster and not at Holyrood.
This move could cause a backlash and mean that Scotland breaks away from the union on a temporary upsurge in strong feelings over London pressure spurred on by the SNP.
This is very dangerous for the union and also for devolved democracy.
The SNP in the Scottish parliament has already overcome the odds in getting elected in a parliament designed to not give a majority to a single party. The Westminster parties should not underestimate the SNP or the First Minister, Alex Salmond.
We also shouldn't fear the 3 options vote as this will split the vote and will mean that the SNP is campaign for two options. A very hard position to hold.
So be careful because people are naturally rebellious when they are dictated to by those with power.
