BP has made its largest global oil and gas discovery in 25 years in Brazil's Santos basin, it said on Monday, in what may be a major boost for the British company's strategic shift away from renewable energy to refocus on fossil fuels.

Energy giant BP says it has made its largest oil and gas discovery this century as it shifts its focus away from renewable energy and back to fossil fuels. The UK-based firm said on Monday that it is conducting tests at the site in deep water off Brazil's west coast.
