The Institute of Chartered Secretaries and Administrators published guidance for companies on the implementation of the Shareholder Rights Directive in the UK. The relevant rules were introduced through changes to the Companies Act 2006 which came into force on 3 August 2009 (see our July 2009 E-Bulletin article: Companies Act 2006: The Company (Shareholders' Rights) Regulations 2009).
