"Dear All,

I am emailing to ask for some specific action which the prime minister plans to announce shortly. This follows a meeting yesterday at No 10 yesterday to discuss a range of child internet safety issues including parental controls and filters. The prime minister would like to make some further specific requests of industry and his office have asked us to ask you when you could deliver the following actions.

1. Implementing browser intercept

I understand that Talk Talk will be trialling a "browser intercept" to force existing customers to choose either to proceed with parental controls (pre-ticked), choose their own settings or turn them off completely. The prime minister wants to announce that by the end of the year, every household with a broadband internet connection will have had to make a decision to "opt-out" of installing filters. Will the other three ISPs consider making a commitment to adopting this approach - even before it has been trialled?

2. Age-verification systems/closed-loop

The prime minister expects customers to be required to prove their age/identity before any changes to the filters are made. I understand that you will all be implementing "closed-loop" systems which will notify account holders of any changes that are made to the filters and that you have robust systems in place but please could you all confirm the precise information that is required to enable customer to access, set-up and change their filters?

3. Awareness campaign for parents

I understand that it was agreed at Claire Perry's meeting a few weeks ago that Talk Talk, BT and others would undertake some further research to establish what the focus of the campaign should be. The prime minister would like to be able to announce a collective financial commitment from industry to fund this campaign. I know that it will be challenging for you to commit to an unknown campaign but please can you indicate what sum you will pledge to this work that the PM can announce.

4. Using the phrase "default-on" instead of "active-choice +"

The prime minister believes that there is much more that we can all do to improve how we communicate the current position on parental internet controls and that there is a need for a simplified message to reassure parents and the public more generally. Without changing what you will be offering (ie active-choice +), the prime minister would like to be able to refer to your solutions are "default-on" as people will have to make a choice not to have the filters (by unticking the box). Can you consider how to include this language (or similar) in the screens that begin the set-up process? For example, "this connection includes family-friendly filters as default [or as standard] - if you do not want to install this protection please un-tick the box" (obviously not intended to be drafting). Would you be able to commit to including "default-on" or similar language both in the set-up screen and public messaging?

We are all aware of the really excellent work that you are doing and but there are a number of specific areas that the prime minister thinks need further immediate action. You are likely to receive a further message from colleagues in DCMS and the Home Office regarding tackling illegal images but given the short deadline for this work we thought it better to give you some time to work on these issues in the meantime. I need to report back to No 10 by the end of the week on these points so I would be grateful if you could consider this request as a matter of urgency and respond by midday Friday.

Apologies for the very tight deadline and grateful for your help with this work."
