"Conclusion
168.Witnesses were unequivocal in stating that losing the protection of the Unregistered Community Design Right would be hugely damaging to the design and fashion industries within the UK. Operating outside the EU regime could mean that the UK loses marketing protections, weakening the UK’s competitive position and undermining major events such as London Fashion Week.  The UK system does not provide sufficient protection on its own and it is evident that protecting the commercial interests of designers and maintaining the pre–eminent position of events such as London Fashion Week can only be achieved via a reciprocal system with comprehensive powers of enforcement.
... we believe it is imperative to negotiate a continuation of EU-wide protection for British businesses."
