Will Gardner, chief executive of internet safety charity Childnet International, said it was an "essential" measure to protect youngsters on the Internet.

"Protecting children from exposure, including accidental exposure, to adult content is incredibly important, given the effect it can have," he said.

"Steps like this to help restrict access, alongside the provision of free parental controls and education, are key. It is essential to help."
