Twitter testing edit button as it trials letting users change tweets after posting

The tweets will appear with an icon, timestamp and label to make clear that the original post has been modified. Tapping the label will take viewers to an edit history, which will include past versions of the tweet.

Twitter announced in April that it was working on an edit button, soon after Elon Musk had held a poll on the subject, although it did not supply much detail.

At the time Twitter said it had been working on the button long before the intervention by Musk, who subsequently agreed to buy the business for $44bn (£38bn) but is now trying to exit the deal.
