With regard to any request from members about e-mails they receive, if they were received on the mail system of the House of Commons, we maintain logs of e-mails and logs of Internet access. All of these logs are maintained for a certain length of time, and we are able to do some investigations.
For example, with regard to all of these videos on YouTube you referred to, there's no doubt that we've done due diligence to scan the computer environments, and I can affirm that none of those videos was posted from any computer from the House of Commons. That's very clear.
That's the extent of it. If it crosses the boundaries of the House and is outside, I don't have access to those tools.
