LONDON: BP returned to profit in the second quarter, the British energy giant said on Tuesday, helped by firmer oil prices and lower charges linked to the Gulf of Mexico spill disaster. Net profit stood at $144 million (122 million euros) in the three months to June 30 compared with a loss after tax of $1.4 billion in the second quarter of 2016, BP said in a results statement. Chief executive Bob Dudley said BP would continue with a “tight focus on costs, efficiency and discipline in capital spending”.
