Re: Add it to the pile
British science has depended, in large part, on trans-European cooperation, and, while we were in the EU, Britain was an attractive place for students and researchers. Now we're cut out of Horizon, and have an actively hostile attitude towards students from our nearest neighbours, there is a definite brain drain.
Even our home-grown bing-pharma industry has become multinationalised and is being siphoned away to the US and the continent. GSK is headquartered in London... for now, but the pattern there is very much of smaller companies being borged by larger ones (I can remember when Glaxo, Wellcome, Smithkline and Beechams were all separate entities). It's only a matter of time before the next merger with someone like Pfizer, and all the research is moved to the US or the Netherlands, where they can actually attract researchers.
