Elon Musk could be hauled before MPs to give evidence about his plans for Twitter.
The Tesla tycoon is buying the social media network for £34.5billion in a deal hailed as a boost for free speech.
However, critics fear moderation will be even looser on the site as the billionaire overhauls rules.
He has been asked to appear before the Commons Digital, Culture, Media and Sport Select Committee to allow MPs to interrogate him on his plans.
DCMS Chairman Julian Knight said: “At a time when social media companies face the prospect of tighter regulations around the world, we’re keen to learn more about how Mr Musk will balance his clear commitment to free speech with new obligations to protect Twitter’s users from online harms.
“Appearing before the committee will give Mr Musk an ideal opportunity to set out his proposals for Twitter in more depth and we would look forward to welcoming him.”
In his letter to Mr Musk, 50, the senior Tory backbencher says the “intention to roll out verification for all users echoes our calls on the UK Government as part of proposed legislation”.
The Government’s flagship Online Safety Bill is going through Parliament - and Mr Knight says his committee’s report on the plan “discussed ways to balance civil liberties like freedom of expression with the need to tackle pernicious, pervasive online child sexual exploitation and abuse”.
He tells Mr Musk: “I therefore wish to take this opportunity to invite you to speak before our Committee and discuss your proposals in more depth.
“I know you have expressed your wish that critics remain on Twitter and this may present an opportunity to address any critiques in public.
“I look forward to hearing your response and discussing your plans for the future of Twitter in committee in the near future.”
Mr Musk has tweeted about plans for Twitter since the proposed takeover was announced - including the suggestion that government and business accounts could face "a slight cost" to stay on the site.
He added that Twitter would "always" be free to "casual users".
The DCMS Committee previously tried to bring Facebook boss Mark Zuckerberg in for questioning but he snubbed their invitation.
