'Help families install filters'

Every household in the UK is to have pornography blocked by their internet provider unless they choose to receive it, David Cameron is to announce.

In addition, the prime minister will say possessing online pornography depicting rape will be illegal.

In a speech, Mr Cameron will warn that access to online pornography is "corroding childhood".

Search engines will be given until October to introduce further measures to block illegal content.

Claire Perry the Prime Minister's advisor on the sexualisation and commercialisation of childhood, told BBC Breakfast that companies need to do more to help families to install family friendly filters.
