Reuters reports that british Prime Minister Boris Johnson cast Scottish devolution as a "disaster" and ruled out any further powers for Edinburgh.

The past 14 opinion surveys have shown that a majority of Scots now support independence after a series of missteps by Johnson's government over its response to the novel coronavirus pandemic.

Johnson said that devolution had been a disaster and former Prime Minister Tony Blair's "biggest mistake", The Sun newspaper reported.

Johnson added that he did not currently "see a case" for giving the devolved government in Edinburgh any more powers from London, The Sun said.

Scots rejected independence by 55 to 45 percent in a 2014 referendum but a five-year political crisis in London over Brexit and the COVID-19 outbreak have strained the bonds that tie the United Kingdom together.
