In Labour's Scottish Bastion, Nationalists Prepare an Upset

In Scotland's biggest city, nationalists have triggered a once-in-a-century shift in political loyalties that could dash Labour leader Ed Miliband's dreams of winning the May 7 election and thrust secessionist 'kingmakers' to the heart of British power. The shifting currents in Glasgow, the citadel of Scottish socialism for more than a century, show the seriousness of the nationalists' bid to end Labour's dominance of Scotland, a significant change in recent British political history. The nationalist challenge could trigger events after the election that threaten the future of the United Kingdom and possibly its membership of the European Union.
