Brexit vote: 'Our EU scientists didn't feel welcome in UK'

The bio-tech industry, which researches new medicines and antibiotics, has been one of the fastest growing sectors of the British economy of the past 20 years, with firms in the sector saying they need to recruit scientists from around the world to do their research.

Dr David Williams, chief executive of Discuva, a biotech company based in Cambridge trying to find an antibiotic for hospital superbugs, says the Leave vote is threatening his ability to recruit and retain the brightest and best scientists from Europe.
