Informal votes are those where the voter has not clearly indicated the option they wish to vote for. This can be because the voter leaves the paper blank, the voter takes deliberate action to spoil the paper, or an error by the voter means that their intention is not clear.

Invalid votes are excluded from the count and include, for example, voting papers that cannot be processed because the voter has made the QR code unreadable, voting papers that have been cancelled as a result of replacement voting papers being issued, or voting papers returned late.
