Constitutional collision course

Sir, – Nicola Sturgeon might very well be right to seek a more flexible approach on post-Brexit immigration policy (Sturgeon immigration call, May 15).

Yet to secure agreement with the UK Government would require a degree of mutual trust in this policy area, which is to say the least highly charged.

Ever since the EU referendum result, our first minister has been putting herself and her government at odds with the UK Government, seemingly setting out to find grounds for sufficient grievance to justify triggering a full blown constitutional crisis. Of course, intermittently, the spectre of an independence referendum is raised, just to ensure the UK Government does not lose sight of the end game. It is perfectly understandable that the UK Government might be reluctant to get into discussions about a flexible immigration policy when it is so obvious that anything they say might be used against them.

While Nicola Sturgeon will try to portray this as further grounds for grievance, many will see the true cause of mistrust being her insistence in choosing confrontation over cooperation at every stage of her dealings with the UK. Keith Howell. White Moss, West Linton.

Donald Dewar must be spinning in his grave at the way this UK Government is treating the Scottish Parliament
