What is Elon Musk doing to Twitter?

More turmoil is surrounding Elon Musk and Twitter as high-profile staff quit and the rules about verified accounts keep changing.

People on and off the social media platform have been raising concerns about the direction Twitter is going in under its new billionaire leader.

As part of his shake-up of the platform, Mr Musk began rolling out plans to allow users to buy blue-tick verified status for $8 per month. The move raised concerns that Twitter would be swamped with fake accounts.

A US regulator says it is watching events at Twitter with "deep concern" after the platform's top privacy and compliance officers reportedly quit.
