The book, available free of charge from the firm’s website, contains all EU legal measures in the areas of listing of securities, prospectus obligations, market manipulation and insider dealing, and transparency and governance.

Paul Egan SC provides an overview in the book of the structure of EU securities regulation.

Since the financial crisis of 2008 the EU has generally moved from adopting Directives, which are transposed into member state law, to adopting directly applicable Regulations, made both by the European Parliament and Council of Ministers and by the European Commission.

The book contains the Directives and Regulations in these areas of the law. In addition, the official guidance on these measures from the European Securities and Markets Authority is included.

Mr Egan said: “EU securities law, as well as being relevant in the EU, will continue to be relevant in the UK, at least for now, notwithstanding Brexit and all the accompanying noise.

“An irony that is missed by many is that much of EU law like this began life in the UK and was then brought forward in the EU with the UK in the driving seat.”
