Why new post-Brexit ‘UKCA’ standard is proving such a headache for industry

At the moment, as Sam Lowe, the trade expert at the Centre for European Reform, explains, this is essentially a duplicative process because UK standards follow EU standards in the “vast majority of cases”.  

...You might think, therefore, that this expression of UK sovereignty (a UK version of a CE mark, for its own sake) is an example of what Lowe calls “performative divergence”, ie of little actual consequence but important to show that Brexit has delivered concrete change.
