Amid a pivot back to its fossil fuel roots and away from renewable energy, Britain's BP said it had made its largest oil and gas discovery in 25 years.

BP is seeking to bolster oil and gas in its portfolio to regain investor confidence and revive underperforming shares.

BP has been under ongoing pressure from investors for underperforming compared to its rivals in recent years. In February, BP slashed its planned investments in renewable energy projects and said it would spend billions of dollars more a year on its oil and gas operations in a bid to improve investor confidence.
