A new law will seek to cover a loophole which means that paedophiles who ask children to send them explicit selfies online could face up to two years on prison.
It comes as part of a raft of new measures unveiled by the government today as part of an international crackdown tackling child sexual exploitation.

Among the measures announced is a global database of abuse imagery, to help the authorities scour the internet for images to help tackle the "appalling and evil trade".
