One of the many reasons the UK left the EU

This is one of the many reasons the UK voted to leave the EU – sovereignty. Regardless of the merits of the particular issue of gender quotas for boards, there is no reason the should be a rule for this across the entire EU.

Why would British firms have to comply with a decision made in Brussels, as opposed to one made in London.

The EU does many many good things, but one of its failings is it regulates far too much from the centre.
