Mumsnet, an online forum for mothers, has withdrawn its support for pornography filters on the web after an angry response from the sites users.
Initially the influential forum had backed plans by the Conservative led government to instruct internet service providers to filter pornography in a bid to prevent children from accessing it.
But an angry backlash from members soon followed, as mums feared the impact of censorship and a shift in responsibility away from parents.
Culture Minister Ed Vaizey has been leading the censorship charge following campaigning from Christian groups. However the policy is at odds with the small government “nudge” agenda which David Cameron avowedly prefers.
