Sturgeon has sent the letter to May formally requesting the transfer of powers to Scotland to hold the second Scottish Independence referendum.
Sturgeon in formal request over independence vote
The letter is quite interesting in that it anticipates the reluctance of May to allow the request.
"However, in anticipation of your refusal to enter into discussions at this stage, it is important for me to be clear about my position.
It is my firm view that the mandate of the Scottish Parliament must be respected and progressed. The question is not if, but how."
Now the next few lines might be upsetting for some as it is, in effect, the declaration of an intention to proceed anyway:
"I hope that will be by constructive discussion between our governments.
However, if that is not yet possible, I will set out to the Scottish Parliament the steps I intend to take to ensure that progress is made towards a referendum."
Could this be Scotland standing up as a nation? Or is it just reading too much into a bit of polite chit-chat?
