Twitter is to allow US users to edit their posts in exchange for a fee after successful trials in Canada and Australia. 

The social media site has launched its premium "Twitter Blue" service in America and New Zealand, giving users access to features such as an undo button which allows them to change a post up to 30 seconds after publishing it.

Subscribers to the service, which costs $2.99 (£2.20) a month, will also be able to read advert-free news articles on websites including The Washington Post and The Atlantic.

Twitter first launched the service in Australia and Canada over the summer and has since been taking feedback from customers.

A spokesman said: "We’ve been listening to and learning from the most passionate and vocal people on Twitter as to what will make their experience more customizable, more frictionless, and simply put – better."

Other features include being able to upload videos of up to ten minutes, compared to two minutes for regular users.

It’s time to flex those Twitter fingers and take it to the next level 💪

Twitter decided to offer a subscription service features after struggling with slowing user growth amid competition from newer rivals such as the video sharing site TikTok.

It began testing another feature last year,  Spaces, allowing users to create live "audio rooms" in what was interpreted as an effort to stop them leaving to join the increasingly popular Clubhouse app. 

Much of Twitter’s income in the past has come from advertising. However, changes to Apple’s privacy policies have made it harder for clients to use apps to collect data and target their ads. According to a recent study, Facebook, YouTube, Twitter and Snapchat lost an estimated $10bn in revenues from the policy shift at Apple. 

Twitter has previously said the advertising changes would have an ongoing but modest impact on sales.
