Any management expert knows that mergers, demergers and acquisitions are among the toughest of business challenges. Merging companies, let alone universities, should be approached with all the caution of porcupines making love.
But our rulers see no need for subtlety when they remodel their political empires. For them, the creation of the Department for Education and Skills - not to mention the Department for Work and Pensions and the Department for the Environment, Food and Rural Affairs - is the work of an afternoon. Quick work for organisations that deal with academics, teachers, the employed, the unemployed, the once employed and, in the shape of pupils and students, the not yet employed - in a word, pretty well the entire population.

It is likely that the worlds of education, research and work will provide some of the biggest challenges to the delivery team. Everyone agrees that skills are the magic ingredient in short supply in the workforce. But deciding which skills are needed for the new-economy Britain promised by Labour is more difficult.
