An A-Z of the EU rules that matter for the economy

The report is based on thousands of conversations with UK businesses, as well as dozens of leading trade associations, and provides an A to Z of the rules that will matter after the transition period. From architects to zoos, it outlines the regulatory needs of 23 industry and service sectors, of which 18 prefer convergence or alignment for the majority of regulation that matters.

The CBI study, compiled over a six-month period, says Brexit presents opportunities for rule changes in sectors such as agriculture, shipping and tourism that could benefit the British economy and consumers.

However, the report adds that these opportunities for divergence are vastly outweighed by the costs of deviating from rules necessary to ensure smooth access to the EU, the UK's largest trading partner.
