Scientists for EU

You should read the Japanese government letter. As one SfEU follower wrote on Twitter: "Almost seems as though the Japanese govt understands what Brexit means better than the British."

The letter puts all the top negotiating cards in EU hands. Basically saying that if negotiations don't preserve almost everything, then Japanese companies in the UK from pharma, tech and manufacturing will relocate to the EU. It even invites the EU to help make this transfer easier. The Japanese government clearly supports freedom of movement - its companies in the UK rely on both skilled and unskilled labour from the EU. The letter says the UK should preserve EU regulations (awkward for those who would throw off "EU chains") and access to EU research programmes. It also wants the European Medicines Agency to stay in London. That's very unlikely to happen.
