Elon Musk, the founder of electric carmaker Tesla and space exploration company SpaceX, has been appointed to Twitter’s board of directors, the company's CEO said on Tuesday.

“I’m excited to share that we’re appointing @elonmusk to our board! Through conversations with Elon in recent weeks, it became clear to us that he would bring great value to our Board,” Parag Agrawal tweeted.

“He’s both a passionate believer and intense critic of the service which is exactly what we need on @Twitter, and in the boardroom, to make us stronger in the long-term. Welcome Elon!”

Musk responded to the tweet and said: "Looking forward to working with Parag & Twitter board to make significant improvements to Twitter in coming months!"

The announcement came a day after Musk purchased a 9.2% share in Twitter, becoming the social media platform’s biggest investor. After the acquisition, Twitter shares surged by around 26% in the market.

After his shareholding in Twitter was made public on Monday, Musk launched a poll asking whether people want an edit button on the platform./aa
