Where special notice is required, such as for resolutions to remove directors (under Section 168 Companies Act 2006), notice of the intention to move the resolution must be given at least 28 days before the meeting at which it is to be moved. If that is not practicable, notice can be given in newspapers (or any other method allowed by the company's articles) at least 14 days before the meeting. The company must then give notice of the resolution when it calls the relevant meeting.
Special notice applies to certain types of resolution that can only be passed at a general meeting.
