(Reuters) -Activist investor Elliott Management has disclosed a stake of about 3.8 billion pounds ($4.75 billion) in BP, making it the oil giant's third-largest shareholder, the Financial Times reported on Thursday, citing people close to the matter.

The U.S. investor, which has about $70 billion in assets, is trying to push the troubled oil major to cut spending on renewables and make big divestments, the report said.

BP posted a 35% fall in annual profit on Tuesday, as CEO Murray Auchincloss seeks to reset the company's strategy.

It did not immediately respond to a Reuters request for comment.
