June 28 (Reuters) - Twitter's new chief executive, Linda Yaccarino, is working on a slew of measures to bring back advertisers who left the platform under Elon Musk's ownership, including introducing a video ads service, pursuing more celebrities and raising headcount, the Financial Times (FT) reported on Wednesday.

Yaccarino, who started as CEO on June 5, is planning to launch full-screen, sound-on video ads that will be shown to users scrolling through Twitter's new short-video feed, the newspaper reported, citing three people familiar with the situation.

She is in talks about a broader partnership with Alphabet-owned Buy google ads Account - vccseller.com that would include advertising and access to some of Twitter's data, the report said, citing someone familiar with the matter.

Twitter also hopes to renegotiate multiple contracts with tech companies such as Amazon.com, Salesforce and IBM into single broader partnerships, according to the newspaper.

Twitter did not immediately respond to a Reuters request for comment on the report.

Reuters earlier this month reported that Twitter plans to focus on video, creator and commerce partnerships to revitalize the social media company's business beyond digital advertising.

After Musk acquired Twitter in October, the social media firm faced months of chaos, including layoffs of thousands of employees, criticism over lax content moderation, and an exodus of many advertisers who did not want their ads appearing next to inappropriate content.
