It would be wrong to say we hold no sway, but clearly alone we are at a distinct disavanage. It's also hard to underestimate the advantages of being able to sperate trade policy handeled by the EU, and UK forign policy. I mean, are China really going to turn down a China/EU trade deal over using Huawei equipment in the UK 5G network? I don't think so. The current protectionist and oftern outright agressive international trade climate makes the EU indespensable for the UK. There could not be a worse time to go it alone.
