Self- or co-regulation for UK ISPs?

Adjournment debate in Parliament - with a very interesting intervention about coding of mobile content. Minister Vaizey (yes, that one) stated: "I mentioned this during my speech on net neutrality last week-that they can manage the traffic that crosses their network in order to give their consumers a good service... It seems to me that, given that rights holders are fully aware of the websites that are distributing their content illegally, ISPs could do more in that regard."
