The UK university system is second only to the vastly bigger US system in its number of internationally top-ranked universities, and in the percentage of overseas students it attracts each year. These are significant achievements, too often overlooked. They were not quickly or easily won. In an increasingly competitive world, they can be quickly and permanently lost.

Within the UK, universities deliver huge benefits, particularly well documented in science, technology and medicine, the greatest of which may be the flow of graduates into the workforce. The most remarked-upon, however, is the rapid expansion of our role as innovators with a significant economic impact. In recent years, high-technology and biotechnology clusters have sprung up around a number of research-intensive universities.

Focusing only on what is most easily measured or o immediate economic impact is to miss the deeper point, of course. Through the arts, humanities and social sciences, this country’s universities contribute broadly to society, adding greatly to human well-being. Although universities are offering their best help in the economic downturn, as institutions we are above all for the students of today who will be the workforce, citizens and leaders of tomorrow; the discoveries that will transform. the future; the scholarly insights that will change the way the world thinks and acts.

What has made the UK system so successful? I point to the quality of water we provide, the talent we attract, and the diversity of strengths that we offer. The diversity of UK universities is partially reflected in our differences in age, size, history, governance, in the makeup of our student bodies, course offerings, the kinds of research we do, the combination of teaching and research, and the balance of academic and professional or pre-professional training.
