Be careful what you wish for, Joanna.

Perhaps SNP MP Joanna Cherry, QC, should be careful about what she wishes for in her seeking to have a court rule that the prime minister could be sent to prison for not sending the Brexit Surrender letter to the EU.

It is not that long ago that her colleagues in the Scottish parliament, in relation to the Named Persons Act, a piece of legislation that would not have been out of place in North Korea, were seeking to ignore a ruling from the Supreme Court when it ruled that the information sharing involved in the scheme breached the European Convention on Human Rights.   

So would she have similarly gone to court to see Mr Swinney going to the Big Hoose, aka the Bar-L, aka Barlinnie Prison for refusing to implement the Supreme Court ruling?   

Thought not.
