Google braces for questions as more big-name firms pull adverts

Vodafone and trio of high street banks take action as industry and UK government ask how their ads became attached to extremist material

Google executives are bracing for a two-pronged inquisition from the advertising industry and the government over the company's plans to stop ads being placed next to extremist material.

A slew of big-name companies, advertising firms and government departments have either pulled their adverts from Google and its YouTube video site or are considering whether to do so, with media giant Sky, telecoms group Vodafone and a trio of banks adding their names to a growing list over the weekend.
