Policy chiefs from Google, Facebook and Twitter are appearing before the Home Affairs Committee over the subject of online abuse.

Google and Facebook have said that by next year they expect to have 10,000 and 7,500 staff all watching, reading and removing violent and extremist content.

Yvette Cooper is immediately taking issue with Sinead McSweeney from Twitter, who, she says, has still not taken down various abusive tweets her office reported from last year.

Extraordinary how Twitter reigns supreme as far as politicians, journalists and the rest care. Facebook and Google (which owns Youtube) are many times larger.
