The School was ranked number one out of more than 80 schools. The ranking combines degree and executive education programmes - the MBA, Executive MBA, Masters in Management and both Open and Custom Executive Education programmes.
Professor Sir Andrew Likierman, Dean, London Business School, said: "We are consistently ranked in the world’s top business schools. Taking the top spot in this year’s FT ranking of European schools is a great end to an exciting year."
The Financial Times highlights the strength of British schools in this year's ranking.
"British business schools shine in the 2015 Financial Times ranking of European institutions. Not only has London Business School (LBS) kept its crown as the best business school in Europe but three other schools in Britain have achieved the biggest rises since last year", writes the Financial Times' Laurent Ortmans.
