The golden triangle refers to the triangle formed by the university cities of Cambridge, London, and Oxford in the south east of England in the United Kingdom. The triangle is occasionally referred to as the Loxbridge triangle, a portmanteau of London and Oxbridge or, when limited to five members, the G5. The golden triangle universities generally include: Imperial College London (ICL) King's College London (KCL) London School of Economics (LSE) University College London (UCL) University of Cambridge University of Oxford The list of universities considered to be members of the golden triangle varies between sources, but typically comprises the University of Cambridge, the University of Oxford, Imperial College London, University College London, King's College London, and the London School of Economics. Some sources omit either or both of King's College London and the London School of Economics. while occasionally other universities are included, e.g. the London Business School and the London School of Hygiene and Tropical Medicine, or all of the higher education institutions in the three cities. Members Golden triangle universities possess some of the largest UK university financial endowments; endowment sizes range from UCL's £139 million (2019) to Cambridge's £6.44 billion (including colleges) Further, each university receives millions of pounds in research fundings and other grants from the UK government, criticised by leaders of some other universities as disproportionate and not in the best interests of the country as a whole. In 2013/14, universities in Oxford, Cambridge and London received 46% of research funding in the UK, up from 42.6% a decade earlier. Research income With the exception of the LSE, the five other institutions typically considered members of the golden triangle (sometimes referred to as the G5) have among the highest research incomes of all British universities, ranking in the top seven of British universities by research grant and contract income (along with Manchester and Edinburgh) and in the top six of English universities by Research England recurrent funding (along with Manchester). These five institutions all have significant fractions of their research grant and contract income from clinical medicine, varying (in 2021/22) from 41.7% (Cambridge) to 63.6% (King's College London), compared to an average across the UK of 34.4%. Overall, 50.9% of the 2020/21 research grant and contract income of the five institutions (50.0% if the LSE is included) came from clinical medicine research, and they accounted for 34.7% of all research grant and contract income of
