The great 'Made in Britain' delusion
Against this backdrop, Britain’s best hope is that it can agree with its trade partners (and Brussels) a system called “cumulated rules of origins,” said Samuel Lowe, a trade expert at the Centre for European Reform. ...“To allow cumulated rules of origins with, for example, South Korea, not only Britain but also the EU would need to negotiate with Seoul,” said Lowe. Every renegotiation comes with a cost, such as counter-demands from the other side, he warned. To reopen the EU’s numerous trade deals would be lengthy and costly.
“There’s not much incentive for the EU to help Britain here,” Lowe said.
