Scotland and the tide below the waves

Powerful article in the Glasgow Herald by Iain Macwhirter on the Calman Commission on Scottish Devolution which everyone in London who is interested in UK politics should read . He reports that Calman is "arguably as
important as the 1988 Claim of Right and the 1997 Devolution white
paper. By making the intellectual case for a degree of fiscal autonomy
so cogently, it has set Scotland on a new course which should lead, at
the very least, to a new federal United Kingdom within 10 years."  Macwhirter says he is astonished that the Tories have agreed  to it and set Britain on course for new settlement. Is Cameron ensuring the English card remains in play despite his professed unionism? (Hat tip Tom Griffin)
