Domain names and email addresses referring to you as an MP
2.12 No one can use the title MP during dissolution and you should not use a website or an email address during dissolution if it suggests you are currently an MP. Any website that contains a URL referring to you as an MP (e.g. johnpeekmp.co.uk) should be frozen. This means the website may remain online, but that no new content should be added except the disclaimer, contact details and/or a link to an alternative web site.
During dissolution there are no MPs, and impersonating an MP may be an offence (have not dug down that deep yet, but it could be along the same lines as impersonating a doctor, and you can make up your own mind which is the most dangerous).
