It took a long time and and a campaign by a guy I don't particularly like, to get the Prime Minister to have an email address. OK, so he probably wouldn't read them himself, but at least you had somewhere to send rants etc. Well not anymore. The contact page of the Number 10 website says
Email Number 10Pretty poor show really, I mean it's just a mailbox, it's not like email hasn't been around for over 30 years now is it?
We have decided at this time that it is important to take another look at the E-mail Number 10 service to ensure that it meets the same high standards as the other content and communication measures that the website delivers.
Unfortunately, this means that we will be unable to replace the service as quickly as we had hoped, but we aim to have it up and running as soon as possible. Please accept our apologies for any inconvenience caused.
