Scotland's papers: 'Dear Theresa' and superbug crisis
A photograph of Nicola Sturgeon curled up, bare-foot, on a couch at Bute House features on the front pages of many of Scotland's newspapers.
In it, she is said to be signing a letter to Prime Minister Theresa May, formally requesting the power to hold a second referendum on Scottish independence.
The Herald reports that Ms Sturgeon signed the document after claiming that the legislation needed to put Brexit into place was a "power grab that would strip Holyrood of its authority".
The dispute was described as "constitutional warfare" by The National. It said the first minister's spokesman had suggested that Holyrood would try to block the Great Repeal Bill, which would transfer thousands of European regulations into British law, should it encroach on Holyrood's authority.
The i leads with the same story, pointing out that the UK government's white paper said it expected the devolved administrations to see a "significant increase" in their decision-making powers.
But it goes on: "However, the document is vague about exactly what will be controlled at a UK level, stating that this will be subject to "intensive discussions" with ministers in Scotland, Wales and Northern Ireland."
The Scotsman says regulations covering everything from the 48-hour working week to the protection of birds will be transferred from Brussels ahead of Brexit, under the Great Repeal Bill.
