ONLY one Scottish university has made it on to a new list of the top 100 institutions in the world.

Edinburgh University rose three places to 46th in the global league table produced by the Times Higher Education Supplement.

The rankings found Cambridge and Oxford were among the most prestigious universities in the world, coming third and fourth, but other UK institutions have lost ground.

A spokesman for Edinburgh University said: "It's always pleasing to perform positively in rankings such as this, but it needs to be borne in mind there is a variety of league tables used to rank universities nationally and internationally. They all use different criteria and positions fluctuate accordingly from year to year."

Researchers warned of a polarisation between the very top institutions in the UK, and the rest, amid increasing competition from Asian nations.

The UK has lost three universities from the top 100 in the last two years, the rankings show.

Harvard in the US took first place in the rankings.
