As countries over the world including India face elections amid the spread of fake news and political interference on social media platforms, Facebook CEO Mark Zuckerberg has asked for some more time to fix his network that has over two billion users.

In a post on Friday, Zuckerberg said that Facebook started on the platform sanitising project in 2017 and "even this work will extend through 2019, I do expect us to end this year on a significantly better trajectory than when we entered it". "My personal challenge for 2018 has been to fix the most important issues facing Facebook -- whether that's defending against election interference by nation states, protecting our community from abuse and harm, or making sure people have control of their information," the Facebook founder wrote.
