Kim Kardashian West and number of other high profile celebrities have announced they will freeze their social media accounts to protest against the spread of "hate, propaganda and misinformation".

Kim Kardashian West has criticised Instagram and Facebook for allowing "the spread of hate, propaganda and misinformation".

The reality star said she would be "freezing" her accounts on the social media platforms on Wednesday and urged others to do the same.

She added that inaccurate social media posts have "a serious impact on our elections and undermines our democracy".

"I love that I can connect directly with you through Instagram and Facebook, but I can't sit by and stay silent while these platforms continue to allow the spreading of hate, propaganda and misinformation - created by groups to sow division and split America apart - only to take steps after people are killed," she said.

She shared the message alongside the #StopHateForProfit hashtag, which is being widely shared by people criticising social media companies.

Kardashian West has 188 million Instagram followers, while her Facebook page has been liked by more than 29,000,000 people.

Other celebrities that have agreed to take part in the boycott include actors Leonardo DiCaprio, Sacha Baron Cohen and Jennifer Lawrence, as well as singer Katy Perry,

"I can't sit idly by while these platforms turn a blind eye to groups and posts spreading hateful disinformation," Perry wrote on Instagram.
