Facebook is promising the social media site's billion users worldwide a new experience.

Chief Executive Mark Zuckerberg is to introduce what's being called a 'dislike' button - an alternative to the 'like' button people already use to show they agree with a post.

Mark Zuckerberg said the company had been asked for the new button by Facebook users.

But he said he didn't want it to be a way of voting down what other people had posted.

We ask what Facebook users in London think about the plan, and discuss further with Mike Butcher, editor-at-large on the TechCrunch website.
