On 29 October 2007, the London Stock Exchange (LSE) published a notice confirming that the changes proposed to the Admission and Disclosure Standards on 30 August 2007 are to be adopted without change. The changes took effect on 1 November 2007. One of the key reasons for the changes was to comply with the additional admission standards introduced by the Markets in Financial Instruments Directive (MiFID).

The updated Admission and Disclosure Standards apply to the admission of all types of securities to the LSE's markets (excluding AIM) and can be found on the LSE website
